SECTION 102.  Compliance Certificates and Opinions.

          Except as otherwise expressly provided by this
Indenture, upon any application or request by the Company to the
Trustee to take any action under any provision of this Indenture,
the Company shall furnish to the Trustee an Officers' Certificate
stating that all conditions precedent, if any, provided for in
this Indenture relating to the proposed action have been complied
with and an Opinion of Counsel stating that in the opinion of
such counsel all such conditions precedent, if any, have been
complied with, except that in the case of any such application or
request as to which the furnishing of such documents is
specifically required by any provision of this Indenture relating
to such particular application or request, no additional
certificate or opinion need be furnished.

          Every certificate or opinion with respect to compliance
with a condition or covenant provided for in this Indenture shall
include:

          (1)  a statement that each individual signing such
     certificate or opinion has read such covenant or condition
     and the definitions herein relating thereto;

          (2)  a brief statement as to the nature and scope of
     the examination or investigation upon which the statements
     or opinions contained in such certificate or opinion are
     based;

          (3)  a statement that, in the opinion of each such
     individual, he has made such examination or investigation as
     is necessary to enable him
     to express an informed opinion as to whether or not such covenant

     complied with.

SECTION 103.  Form of Documents Delivered to Trustee.

          In any case where several matters are required to be
certified by, or covered by an opinion of, any specified Person,
it is not necessary that all such matters be certified by, or
covered by the opinion of, only one such Person, or that they be
so certified or covered by only one document, but one such Person
may certify or give an opinion with respect to some matters and
one or more other such Persons as to other matters, and any such
Person may certify or give an opinion as to such matters in one
or several documents.

          Any certificate or opinion of an officer of the Company
may be based, insofar as it relates to legal matters, upon a
certificate or opinion of, or representations by, counsel, unless
such officer knows, or in the exercise of reasonable care should
know, that the certificate or opinion or representations with
respect to the matters upon which his certificate or opinion is
based are erroneous.  Any such certificate or Opinion of Counsel
may be based, insofar as it relates to factual matters, upon a
certificate or opinion of, or representations by, an officer or
officers of the Company stating that the information with respect
to such factual matters is in the possession of the Company,
unless such counsel knows, or in the exercise of reasonable care
should know, that the certificate or opinion or representations
with respect to such matters are erroneous.

          Where any Person is required to make, give or execute
two or more applications, requests, consents, certificates,
statements, opinions or other instruments under this Indenture,
they may, but need not, be consolidated and form one instrument.

SECTION 104.  Acts of Holders.

          (a)  Any request, demand, authorization, direction,
notice, consent, waiver or other action provided by this
Indenture to be given or taken by Holders may be embodied in and
evidenced by one or more instruments of substantially similar
tenor signed by such Holders in Person or by agent duly appointed
in writing; and, except as herein otherwise expressly provided,
such action shall become effective when such instrument or
instruments are delivered to the Trustee and, where it is hereby
expressly required, to the Company.  Such instrument or
instruments (and the action embodied therein and evidenced
thereby) are herein sometimes referred to as the "Act" of the
Holders signing such instrument or instruments.  Proof of
execution of any such instrument or of a writing appointing any
such agent shall be sufficient for any purpose of this Indenture
and (subject to Section 601 hereof) conclusive in favor of the
Trustee and the Company, if made in the manner provided in this
Section 104.

          Without limiting the generality of the foregoing,
unless otherwise established in or pursuant to a Board Resolution
or set forth or determined in an Officers' Certificate, or
established in one or more indentures
supplemental hereto, pursuant to Section 301 hereof, a Holder,
including a Depositary that is a Holder of a Global Security, may
make, give or take, by a proxy, or proxies, duly appointed in
writing, any request, demand, authorization, direction, notice,
consent, waiver or other action provided in this Indenture to be
made, given or taken by Holders, and a Depositary that is a
Holder of a Global Security may provide its proxy or proxies to
the beneficial owners of interests in any such Global Security
through such Depositary's standing instructions and customary
practices.

          (b)  The fact and date of the execution by any Person
of any such instrument, writing or proxy may be proved by the
affidavit of a witness of such execution or by a certificate of a
notary public or other officer authorized by law to take
acknowledgments of deeds, certifying that the individual signing
such instrument, writing or proxy acknowledged to him the
execution thereof.  Where such execution is by a signer acting in
a capacity other than his individual capacity, such certificate
or affidavit shall also constitute sufficient proof of his
authority.  The fact and date of the execution of any such
instrument, writing or proxy, or the authority of the Person
executing the same, may also be proved in any other manner which
the Trustee deems sufficient.

          (c)  The ownership of Securities shall be proved by the
Security Register.

          (d)  Any request, demand, authorization, direction,
notice, consent, waiver or other Act of the Holder of any
Security shall bind every future Holder of the same Security and
the Holder of every Security issued upon the registration of
transfer thereof or in exchange therefor or in lieu thereof in
respect of anything done, omitted or suffered to be done by the
Trustee or the Company in reliance thereon, whether or not
notation of such action is made upon such Security.

          (e)  The Company may set any day as the record date for
the purpose of determining the Holders of Outstanding Securities
of any series entitled to make any request or demand, or give any
authorization, direction, notice, consent or waiver, or take any
other action, provided or permitted by this Indenture to be made,
given or taken by Holders of Securities of such series.

          With regard to any record date set pursuant to this
paragraph, the Holders of Outstanding Securities of the relevant
series on such record date (or their duly appointed agents), and
only such Persons, shall be entitled to take relevant action,
whether or not such Holders remain Holders after such record
date.  With regard to any action that may be taken hereunder only
by Holders of a requisite principal amount of Outstanding
Securities of any series (or their duly appointed agents) and for
which a record date is set pursuant to this paragraph, the
Company may, at its option, set an expiration date after which no
such action purported to be taken by any Holder shall be
effective hereunder unless taken on or prior to such expiration
date by Holders of the requisite principal amount of Outstanding
Securities of such series on such record date (or their duly
appointed agents).  On or prior to any expiration date set
pursuant to this paragraph, the Company may, on one or more
occasions at its option, extend such expiration date to any later
date.  Nothing in this paragraph shall prevent any Holder (or any
duly appointed agent thereof) from taking, at any time, any action 
contrary to or different from, any action previously taken, or 
purported to have been taken, hereunder by such Holder, in which 
event the Company may set a record date in respect thereof pursuant 
to this paragraph.  Notwithstanding the foregoing or the Trust Indenture
Act, the Company shall not set a record date for, and the
provisions of this paragraph shall not apply with respect to, any
action to be taken by Holders pursuant to Section 501, 502 or 512
hereof.

     Upon receipt by the Trustee of notice of any default
described in Section 501 hereof, any declaration of acceleration,
or any rescission and annulment of any such declaration, pursuant
to Section 502 hereof or of any direction in accordance with
Section 512 hereof, a record date shall automatically and without
any other action by any Person be set for the purpose of
determining the Holders of Outstanding Securities of the series
entitled to join in such notice, declaration, or rescission and
annulment, or direction, as the case may be, which record date
shall be the close of business on the day the Trustee receives
such notice, declaration, rescission and annulment or direction,
as the case may be.  The Holders of Outstanding Securities of
such series on such record date (or their duly appointed agent),
and only such Persons, shall be entitled to join in such notice,
declaration, rescission and annulment, or direction, as the case
may be, whether or not such Holders remain Holders after such
record date; provided that, unless such notice, declaration,
rescission and annulment, or direction, as the case may be, shall
have become effective by virtue of Holders of the requisite
principal amount of Outstanding Securities of such series on such
record date (or their duly appointed agents) having joined
therein on or prior to the 90th day after such record date, such
notice of default, declaration, or rescission and annulment or
direction given or made by the Holders, as the case may be, shall
automatically and without any action by any Person be canceled
and of no further effect.  Nothing in this paragraph shall
prevent a Holder (or a duly appointed agent thereof) from giving,
before or after the expiration of such 90-day period, a notice of
default, a declaration of acceleration, a rescission and
annulment of a declaration of acceleration or a direction in
accordance with Section 512 hereof, contrary to or different
from, or, after the expiration of such period, identical to, a
previously given notice, declaration, rescission and annulment,
or direction, as the case may be, that has been canceled pursuant
to the proviso to the preceding sentence, in which event a new
record date in respect thereof shall be set pursuant to this
paragraph.

SECTION 105.  Notices, Etc., to Trustee and Company.

          Any request, demand, authorization, direction, notice,
consent, waiver or Act of Holders or other document provided or
permitted by this Indenture to be made upon, given or furnished
to, or filed with,

          (1)  the Trustee by any Holder, the First Mortgage
     Trustee or by the Company shall be sufficient for every
     purpose hereunder if made, given, furnished or filed in
     writing to or with the Trustee at its Corporate Trust
     Office, or

          (2)  the Company by the Trustee or by any Holder shall
     be sufficient for every purpose hereunder (unless otherwise
     herein expressly provided) if in writing and mailed,
     first-class postage
     prepaid, to the Company addressed to it at the address of its
     principal office specified in the first paragraph of this
     instrument or at any other address previously furnished in
     writing to the Trustee by the Company.

SECTION 106.  Notice to Holders; Waiver.

          Where this Indenture provides for notice to Holders of
any event, such notice shall be sufficiently given (unless
otherwise herein expressly provided) if in writing and mailed,
first-class postage prepaid, to each Holder affected by such
event, at his address as it appears in the Security Register, not
later than the latest date, and not earlier than the earliest
date, prescribed for the giving of such notice.  In any case
where notice to Holders is given by mail, neither the failure to
mail such notice, nor any defect in any notice so mailed, to any
particular Holder shall affect the sufficiency of such notice
with respect to other Holders.  Where this Indenture provides for
notice in any manner, such notice may be waived in writing by the
Person entitled to receive such notice, either before or after
the event, and such waiver shall be the equivalent of such
notice.  Waivers of notice by Holders shall be filed with the
Trustee, but such filing shall not be a condition precedent to
the validity of any action taken in reliance upon such waiver.

          In case by reason of the suspension of regular mail
service or by reason of any other cause it shall be impracticable
to give such notice by mail, then such notification as shall be
made at the direction of the Company in a manner reasonably
calculated, to the extent practicable under the circumstances, to
provide prompt notice shall constitute a sufficient notification
for every purpose hereunder.

SECTION 107.  Conflict with Trust Indenture Act.

          If any provision hereof limits, qualifies or conflicts
with any provision of the Trust Indenture Act or another
provision which is required or deemed to be included in this
Indenture by any of the provisions of the Trust Indenture Act,
the provision or requirement of the Trust Indenture Act shall
control.  If any provision of this Indenture modifies or excludes
any provision of the Trust Indenture Act that may be so modified
or excluded, such provision of the Trust Indenture Act shall be
deemed to apply to this Indenture as so modified or excluded, as
the case may be.

SECTION 108.  Effect of Headings and Table of Contents.

          The Article and Section headings herein and the Table
of Contents are for convenience only and shall not affect the
construction hereof.

SECTION 109.  Successors and Assigns.

          All covenants and agreements in this Indenture by the
Company shall bind its successors and assigns, whether so
expressed or not.

SECTION 110.  Separability Clause.

          In case any provision in this Indenture or in the
Securities shall be invalid, illegal or unenforceable, the
validity, legality and enforceability of the remaining provisions
shall not in any way be affected or impaired thereby.

SECTION 111.  Benefits of Indenture.

          Nothing in this Indenture or in the Securities, express
or implied, shall give to any Person, other than the parties
hereto and their successors hereunder and the Holders, any
benefit or any legal or equitable right, remedy or claim under
this Indenture.

SECTION 112.  Governing Law.

          This Indenture and the Securities shall be governed by
and construed in accordance with the laws of the State of New
York.

SECTION 113.  Legal Holidays.

          In any case where any Interest Payment Date, Redemption
Date or Stated Maturity of any Security shall not be a Business
Day at any Place of Payment, then (notwithstanding any other
provision of this Indenture or of the Securities) payment of
interest, if any, or principal (and premium, if any) need not be
made at such Place of Payment on such date, but may be made on
the next succeeding Business Day at such Place of Payment with
the same force and effect as if made on the Interest Payment Date
or Redemption Date, or at the Stated Maturity, provided that no
interest shall accrue for the period from and after such Interest
Payment Date, Redemption Date or Stated Maturity, as the case may
be.

SECTION 114.  No Recourse Against Others.

          No recourse for the payment of the principal of or any
premium or interest on any Security or any Senior Note Mortgage
Bond, or for any claim based thereon or otherwise in respect
thereof, and no recourse under or upon any obligation, covenant
or agreement of the Company, contained in this Indenture or the
First Mortgage Indenture or in any supplemental indenture, or in
any Security or any Senior Note Mortgage Bond, or because of the
creation of any indebtedness represented thereby, shall be had
against any incorporator, stockholder, officer or director, as
such, past, present or future, of the Company or any successor
corporation, either directly or through the Company or any
successor corporation, whether by virtue of any constitution,
statute or rule of law, or by the enforcement of any assessment
or penalty or otherwise; it being expressly understood that all
such liability is hereby expressly waived and released as a
condition of, and as a consideration for, the execution of this
Indenture and the issuance of the Securities.

                         SECURITY FORMS

SECTION 201.  Forms Generally.

          The Securities of each series shall be in substantially
the form set forth in this Article, or in such other form as
shall be established by or pursuant to a Board Resolution or in
one or more indentures supplemental hereto, in each case with
such appropriate insertions, omissions, substitutions and other
variations as are required or permitted by this Indenture, and
may have such letters, numbers or other marks of identification
and such legends or endorsements placed thereon as may be
required to comply with the rules of any securities exchange or
as may, consistently herewith, be determined by the officer or
officers executing such Securities, as evidenced by the officer's
or officers' execution of the Securities.  If the form of
Securities of any series is established by action taken pursuant
to a Board Resolution, a copy of an appropriate record of such
action shall be certified by an authorized officer of the
Company, and delivered to the Trustee at or prior to the delivery
of the Company Order contemplated by Section 303 hereof for the
authentication and delivery of such Securities.

          The Trustee's certificates of authentication shall be

          The definitive Securities shall be printed,

officers executing such Securities, as evidenced by the officer's

SECTION 202.  Form of Face of Security.

          [If the Security is to be a Global Security, insert -
This Security is a Global Security within the meaning of the
Indenture hereinafter referred to and is registered in the name
of a Depositary or a nominee of a Depositary.  This Security is
exchangeable for Securities registered in the name of a person
other than the Depositary or its nominee only in the limited
circumstances described in the Indenture, and no transfer of this
Security (other than a transfer of this Security as a whole by
the Depositary to a nominee of the Depositary or by a nominee of
the Depositary to the Depositary or another nominee of the
Depositary) may be registered except in limited circumstances.

          Unless this Global Security is presented by an
authorized representative of The Depository Trust Company, a New
York corporation ("DTC") to the issuer or its agent for
registration of transfer, exchange or payment, and any definitive
Security is issued in the name of Cede & Co. or in such other
name as is requested by an authorized representative of DTC (and
any payment is made to Cede & Co. or to such other entity as is
requested by an authorized representative of DTC), ANY TRANSFER,
PLEDGE, OR OTHER USE HEREOF FOR VALUE OR OTHERWISE BY OR TO ANY
PERSON IS WRONGFUL in as much as the registered owner hereof,
Cede & Co., has an interest herein.]

extent that the payment of such interest shall be legally
enforceable), which shall accrue from the date of such default in
payment to the date payment of such principal has been made or
duly provided for.  Interest on any overdue principal shall be
payable on demand.  Any such interest on any overdue principal
that is not so paid on demand shall bear interest at the rate of
[yield to maturity]% per annum (to the extent that the payment of
such interest shall be legally enforceable), which shall accrue
from the date of such demand for payment to the date payment of
such interest has been made or duly provided for, and such

not a Global Security, insert -- provided, however, that at the
option of the Company payment of interest may be made by check
mailed to the address of the Person entitled thereto as such
address shall appear in the Security Register] [If this Security
is a Global Security, insert applicable manner of payment].

          Reference is hereby made to the further provisions of
this Security set forth on the reverse hereof, which further
provisions shall for all purposes have the same effect as if set
forth at this place.

Securities of any series shall be executed by such additional

hereof.  The signature of any of these officers on the Securities

          Securities bearing the manual or facsimile signature of
any individual who was at any time the proper officer of the
Company shall bind the Company, notwithstanding that such
individual has ceased to hold such office prior to the
authentication and delivery of such Securities or did not hold
such office at the date of authentication of such Securities.

          At any time and from time to time after the execution

Securities of any series executed by the Company to the Trustee

Company Order shall authenticate and deliver such Securities.  If

established in or pursuant to one or more Board Resolutions as
permitted by Sections 201 and 301 hereof, in authenticating such
Securities, and accepting the additional responsibilities under
this Indenture in relation to such Securities, the Trustee shall
be entitled to receive, and (subject to Section 601 hereof) shall
be fully protected in relying upon, an Opinion of Counsel
stating,

          (a)  if the form of such Securities has been
     established by or pursuant to Board Resolution as permitted
     by Section 201 hereof, that such form has been established
     in conformity with the provisions of this Indenture;

          (b)  if the terms of such Securities have been
     established by or pursuant to Board Resolution as permitted
     by Section 301 hereof, that such terms have been established
     in conformity with the provisions of this Indenture;

          (c)  that such Securities, when authenticated and
     delivered by the Trustee and issued by the Company in the
     manner and subject to any conditions specified in such
     Opinion of Counsel, will constitute valid and legally
     binding obligations of the Company, enforceable in
     accordance with their terms, except as may be limited by
     bankruptcy, insolvency, reorganization, moratorium,
     fraudulent conveyance or transfer or other similar laws
     relating to or affecting the rights of creditors generally
     and except as the enforceability thereof is subject to the
     application of general principles of equity (regardless of
     whether considered in a proceeding in equity or at law),
     including, without limitation, (i) the possible
     unavailability of specific performance, injunctive relief or
     any other equitable remedy and (ii) concepts of materiality,
     reasonableness, good faith and fair dealing;

          (d) if prior to the Release Date, that the Senior Note
     Mortgage Bonds to be delivered to the Trustee in connection
     with the issuance of such series of Securities have been duly 
     authorized, and that such Senior Note Mortgage Bonds, when 
     authenticated and delivered by the First Mortgage Trustee and 
     issued by the  Company in accordance with the terms of the First 
     Mortgage Indenture, will constitute valid and legally binding
     obligations of the Company, enforceable in accordance with
     their terms, except as may be limited by bankruptcy,
     insolvency, reorganization, moratorium, fraudulent
     conveyance or transfer or other similar laws relating to or
     affecting the rights of creditors generally and except as
     the enforceability thereof is subject to the application of
     general principles of equity (regardless of whether
     considered in a proceeding in equity or at law), including,
     without limitation, (i) the possible unavailability of
     specific performance, injunctive relief or any other
     equitable remedy and (ii) concepts of materiality,
     reasonableness, good faith and fair dealing, and except as
     enforcement of remedial and procedural provisions thereof
     may be limited by state laws affecting the remedies for the
     enforcement of the security provided for in the First
     Mortgage Indenture; and that such Senior Note Mortgage Bonds
     will be entitled to the benefit of the First Mortgage
     Indenture, equally and ratably, with all other First
     Mortgage Bonds outstanding thereunder, except as to sinking
     fund provisions; and

          (e) if prior to the Release Date, that the First
     Mortgage Indenture and any required financing statements
     have been duly filed and recorded in all places where such
     filing or recording is necessary for the perfection or
     preservation of the lien of the First Mortgage Indenture,
     and the First Mortgage Indenture constitutes a valid and
     perfected first lien upon the property purported to be
     covered thereby, subject only to permissible encumbrances
     (as defined in the First Mortgage Indenture).

If such form or terms have been so established, the Trustee shall
not be required to authenticate such Securities if the issue of
such Securities pursuant to this Indenture will affect the
Trustee's own rights, duties, protections or immunities under the
Securities and this Indenture or otherwise in a manner which is
not reasonably acceptable to the Trustee.

          Notwithstanding the provisions of Section 301 hereof
and of the preceding paragraph, if all Securities of a series are
not to be originally issued at one time, it shall not be
necessary to deliver the Board Resolution, the Officers'
Certificate, or an indenture supplemental hereto otherwise
required pursuant to Section 301 hereof or the Company Order, the
Officers' Certificate, the certificate of an Expert, the Senior
Note Mortgage Bonds and the Opinion of Counsel otherwise required
pursuant to such preceding paragraph at or prior to the time of
authentication of each Security of such series if such documents
are delivered at or prior to the time of authentication upon
original issuance of the first Security of such series to be
issued.  If all of the Securities of a series are not
authenticated and issued at one time, for each issuance of
Securities after the initial issuance of Securities, the Company
shall be required only to deliver to the Trustee the Security
executed by the Company together with a Company Order to the
Trustee to authenticate such Security and to deliver such
Security in accordance with the instructions specified by such
Company Order.  Any such Company Order shall constitute a
representation and warranty by the Company that the statements
made in the Officers' Certificate delivered to the Trustee prior
to the authentication and issuance of the first Security of such 
series are true and correct on the date thereof as if made on and 
as of the date thereof.

          Each Security shall be dated the date of its
authentication.

          No Security shall be entitled to any benefit under this
Indenture or be valid or obligatory for any purpose unless there
appears on such Security a certificate of authentication
substantially in the form provided for herein executed by the
Trustee by manual signature, and such certificate upon any
Security shall be conclusive evidence, and the only evidence,
that such Security has been duly authenticated and delivered
hereunder and is entitled to the benefits of this Indenture.
Notwithstanding the foregoing, if any Security shall have been
authenticated and delivered hereunder but never issued and sold
by the Company, and the Company shall deliver such Security to
the Trustee for cancellation as provided in Section 309 hereof
together with a written statement (which need not comply with
Section 102 hereof and need not be accompanied by an Opinion of
Counsel) stating that such Security has never been issued and
sold by the Company, for all purposes of this Indenture such
Security shall be deemed never to have been authenticated and
delivered hereunder and shall never be entitled to the benefits
of this Indenture.

SECTION 304.  Temporary Securities.

          Pending the preparation of definitive Securities of any
series, the Company may execute, and upon Company Order the
Trustee shall authenticate and deliver, temporary Securities
which are printed, lithographed, typewritten, mimeographed or
otherwise produced, in any authorized denomination, substantially
of the tenor of the definitive Securities in lieu of which they
are issued and with such appropriate insertions, omissions,
substitutions and other variations as the officer or officers
executing such Securities may determine, as evidenced by their
execution of such Securities.

          If temporary Securities of any series are issued, the
Company will cause definitive Securities of that series to be
prepared without unreasonable delay.  After the preparation of
definitive Securities of such series, the temporary Securities of
such series shall be exchangeable for definitive Securities of
such series upon surrender of the temporary Securities of such
series at the office or agency of the Company in a Place of
Payment for that series, without charge to the Holder.  Upon
surrender for cancellation of any one or more temporary
Securities of any series the Company shall execute and the
Trustee shall authenticate and deliver in exchange therefor a
like principal amount of definitive Securities of the same series
and of like tenor of authorized denominations.  Until so
exchanged the temporary Securities of any series shall in all
respects be entitled to the same benefits under this Indenture as
definitive Securities of such series.

SECTION 305.   Registration, Registration of Transfer and
               Exchange.

          The Company shall cause to be kept at the Corporate
Trust Office of the Trustee a register (the register maintained
in such office and in any other office or agency of the Company
in a Place of Payment being herein sometimes collectively
referred to as the "Security Register") in which, subject to such
reasonable regulations as it may prescribe, the Company shall
provide for the registration of Securities and of transfers of
Securities. The Trustee is hereby appointed "Security Registrar" for the
purpose of registering Securities and transfers of Securities as
herein provided.

          Upon surrender for registration of transfer of any
Security of any series at the office or agency in a Place of
Payment for that series, the Company shall execute, and the
Trustee shall authenticate and deliver, in the name of the
designated transferee or transferees, one or more new Securities
of the same series, of any authorized denominations and of a like
aggregate principal amount and tenor.

          At the option of the Holder, any Security or Securities
of any series, other than a Global Security, may be exchanged for
other Securities of the same series, of any authorized
denominations and of a like aggregate principal amount and tenor,
upon surrender of the Securities to be exchanged at such office
or agency.  Whenever any Securities are so surrendered for
exchange, the Company shall execute, and the Trustee shall
authenticate and deliver, the Securities which the Holder making
the exchange is entitled to receive.

          All Securities issued upon any registration of transfer
or exchange of Securities shall be the valid obligations of the
Company, evidencing the same debt, and entitled to the same
benefits under this Indenture, as the Securities surrendered upon
such registration of transfer or exchange.

          Every Security presented or surrendered for
registration of transfer or for exchange shall (if so required by
the Company or the Trustee) be duly endorsed, or be accompanied
by a written instrument of transfer in form satisfactory to the
Company and the Security Registrar duly executed, by the Holder
thereof or his attorney duly authorized in writing.

          No service charge shall be made to the Holder for any
registration of transfer or exchange of Securities, but the
Company may require payment of a sum sufficient to cover any tax
or other governmental charge that may be imposed in connection
with any registration of transfer or exchange of Securities,
other than exchanges pursuant to Sections 304, 906 or 1107 hereof
not involving any transfer.

          The Company shall not be required (i) to issue,
register the transfer of or exchange Securities of any series
during a period beginning at the opening of business 15 days
before the day of the mailing of a notice of redemption of
Securities of that series selected for redemption under Section
1103 hereof and ending at the close of business on the day of
such mailing, or (ii) to register the transfer of or exchange any
Security so selected for redemption in whole or in part, except
the unredeemed portion of any Security being redeemed in part.

          The provisions of this Section 305 are, with respect to
any Global Security, subject to Section 311 hereof.

SECTION 306.  Mutilated, Destroyed, Lost and Stolen Securities.

          If any mutilated Security is surrendered to the
Trustee, the Company shall execute and the Trustee shall
authenticate and deliver in
exchange therefor a new Security of the same series and of like
tenor and principal amount and bearing a number not
contemporaneously outstanding.

          If there shall be delivered to the Company and the
Trustee (i) evidence to their satisfaction of the destruction,
loss or theft of any Security and (ii) such security or indemnity
as may be required by them to save each of them and any agent of
either of them harmless, then, in the absence of notice to the
Company or the Trustee that such Security has been acquired by a
bona fide purchaser, the Company shall execute and upon its
request the Trustee shall authenticate and deliver, in lieu of
any such destroyed, lost or stolen Security, a new Security of
the same series and of like tenor and principal amount and
bearing a number not contemporaneously outstanding.

          In case any such mutilated, destroyed, lost or stolen
Security has become or is about to become due and payable, the
Company in its discretion may, instead of issuing a new Security,
pay such Security.

          Upon the issuance of any new Security under this
Section 306, the Company may require the payment of a sum
sufficient to cover any tax or other governmental charge that may
be imposed in relation thereto and any other expenses (including
the fees and expenses of the Trustee) connected therewith.

          Every new Security of any series issued pursuant to
this Section 306 in lieu of any destroyed, lost or stolen
Security shall constitute an original additional contractual
obligation of the Company, whether or not the destroyed, lost or
stolen Security shall be at any time enforceable by anyone, and
shall be entitled to all the benefits of this Indenture equally
and proportionately with any and all other Securities of that
series duly issued hereunder.

          The provisions of this Section 306 are exclusive and
shall preclude (to the extent lawful) all other rights and
remedies with respect to the replacement or payment of mutilated,
destroyed, lost or stolen Securities.

SECTION 307.  Payment of Interest; Interest Rights Preserved.

          Interest on any Security which is payable, and is
punctually paid or duly provided for, on any Interest Payment
Date shall be paid to the Person in whose name that Security (or
one or more Predecessor Securities) is registered at the close of
business on the Regular Record Date for such interest.

          Any interest on any Security of any series which is
payable, but is not punctually paid or duly provided for, on any
Interest Payment Date (herein called "Defaulted Interest") shall
forthwith cease to be payable to the Holder on the relevant
Regular Record Date by virtue of having been such Holder, and
such Defaulted Interest may be paid by the Company, at its
election in each case, as provided in Clause (1) or (2) below:

          (1)  The Company may elect to make payment of any
     Defaulted Interest to the Persons in whose names the
     Securities of such series (or their respective Predecessor
     Securities) are registered at the close of business on a
     Special Record Date for the payment of such Defaulted
     Interest, which shall be fixed in the following manner.  The
     Company shall notify the Trustee in writing of the amount of
     Defaulted Interest proposed to be paid on each Security of
     such series and the date of the proposed payment, and at the
     same time the Company shall deposit with the Trustee an
     amount of money equal to the aggregate amount proposed to be
     paid in respect of such Defaulted Interest or shall make
     arrangements satisfactory to the Trustee for such deposit
     prior to the date of the proposed payment, such money when
     deposited to be held in trust for the benefit of the Persons
     entitled to such Defaulted Interest as in this Clause
     provided.  Thereupon the Trustee shall fix a Special Record
     Date for the payment of such Defaulted Interest which shall
     be not more than 15 days and not less than 10 days prior to
     the date of the proposed payment and not less than 10 days
     after the receipt by the Trustee of the notice of the
     proposed payment.  The Trustee shall promptly notify the
     Company of such Special Record Date and, in the name and at
     the expense of the Company, shall cause notice of the
     proposed payment of such Defaulted Interest and the Special
     Record Date therefor to be mailed, first-class postage
     prepaid, to each Holder of Securities of such series at his
     address as it appears in the Security Register, not less
     than 10 days prior to such Special Record Date.  Notice of
     the proposed payment of such Defaulted Interest and the
     Special Record Date therefor having been so mailed, such
     Defaulted Interest shall be paid to the Persons in whose
     names the Securities of such series (or their respective
     Predecessor Securities) are registered at the close of
     business on such Special Record Date and shall no longer be
     payable pursuant to the following Clause (2).

          (2)  The Company may make payment of any Defaulted
     Interest on the Securities of any series in any other lawful
     manner not inconsistent with the requirements of any
     securities exchange on which such Securities may be listed,
     and upon such notice as may be required by such exchange,
     if, after notice given by the Company to the Trustee of the
     proposed payment pursuant to this Clause, such manner of
     payment shall be deemed practicable by the Trustee.

          Subject to the foregoing provisions of this Section
307, each Security delivered under this Indenture upon
registration of transfer of or in exchange for or in lieu of any
other Security shall carry the rights to interest accrued and
unpaid, and to accrue, which were carried by such other Security.
SECTION 308.  Persons Deemed Owners.

          Prior to due presentment of a Security for registration
of transfer, the Company, the Trustee and any agent of the
Company or the Trustee may treat the Person in whose name such
Security is registered as the owner of such Security for the
purpose of receiving payment of principal of (and premium, if
any) and (subject to Section 307 hereof) interest, if any, on
such Security and for all other purposes whatsoever, whether or
not such Security be overdue, and neither the Company, the
Trustee nor any agent of the Company or the Trustee shall be
affected by notice to the contrary.  All such payments so made to
any such person, or upon such person's order, shall be valid,
and, to the extent of the sums so paid, effectual to satisfy and
discharge the liability for moneys payable upon any such
Security.

          No holder of any beneficial interest in any Global
Security held on its behalf by a Depositary shall have any rights
under this Indenture with respect to such Global Security, and
such Depositary may be treated by the Company, the Trustee, and
any agent of the Corporation or the Trustee as the owner of such
Global Security for all purposes whatsoever.  Notwithstanding the
foregoing, nothing herein shall impair, as between a Depositary
and such holders of beneficial interests, the operation of
customary practices governing the exercise of the rights of the
Depositary as holder of any Security.

SECTION 309.  Cancellation.

          All Securities surrendered for payment, redemption,
registration of transfer or exchange or for credit against any
sinking fund payment shall, if surrendered to any Person other
than the Trustee, be delivered to the Trustee and shall be
promptly canceled by it.  The Company may at any time deliver to
the Trustee for cancellation any Securities previously
authenticated and delivered hereunder which the Company may have
acquired in any manner whatsoever, and all Securities so
delivered shall be promptly canceled by the Trustee.  No
Securities shall be authenticated in lieu of or in exchange for
any Securities canceled as provided in this Section 309, except
as expressly permitted by this Indenture.  All canceled
Securities held by the Trustee shall be disposed of as directed
by a Company Order.

SECTION 310.  Computation of Interest.

          Except as otherwise specified as contemplated by
Section 301 hereof for Securities of any series, interest, if
any, on the Securities of each series shall be computed on the
basis of a 360-day year of twelve 30-day months.

SECTION 311.  Global Securities.

          If the Company shall establish pursuant to Section 301
hereof that the Securities of a particular series are to be
issued in the form of a Global Security, then the Company shall
execute and the Trustee shall, in accordance with Section 303
hereof, authenticate and deliver, a Global Security or Securities
which (i) shall represent, and shall be denominated in an
aggregate amount equal to the aggregate principal amount of, all
of the Outstanding Securities of such series, (ii) shall be
registered in the name of the Depositary or its nominee, (iii)
shall be delivered by the Trustee to the Depositary or pursuant
to the Depositary's instruction and (iv) shall bear a legend
substantially to the following effect:

          "This Security is a Global Security within the meaning
     of the Indenture hereinafter referred to and is registered
     in the name of a Depositary or a nominee of a Depositary.
     This Security is exchangeable for Securities registered in
     the name of a person other than the Depositary or its
     nominee only in the limited circumstances described in the
     Indenture, and no transfer of this Security (other than a
     transfer of this Security as a whole by the Depositary to a
     nominee of the Depositary or by a nominee of the Depositary
     to the Depositary or another nominee of the Depositary) may
     be registered except in limited circumstances.

          Unless this Global Security is presented by an
     authorized representative of the Depositary to the Company
     or its agent for registration of transfer, exchange or
     payment, and any definitive Security is issued in the name
     of [Cede & Co.] or in such other name as is requested by an
     authorized representative of the Depositary (and any payment
     is made to [Cede & Co.] or to such other entity as is
     requested by an authorized representative of the
     Depositary), ANY TRANSFER, PLEDGE OR OTHER USE HEREOF FOR
     VALUE OR OTHERWISE BY OR TO ANY PERSON IS WRONGFUL in as
     much as the registered owner hereof, [Cede & Co.], has an
     interest herein."

          Notwithstanding the provisions of Section 305 hereof,
the Global Security of a series may be transferred, in whole but
not in part and in the manner provided in Section 305 hereof,
only to another nominee of the Depositary for such series, or to
a successor Depositary for such series selected or approved by
the Company or to a nominee of such successor Depositary.

          If (i) at any time the Depositary for a series of
Securities notifies the Company that it is unwilling or unable to
continue as Depositary for such series or if at any time the
Depositary for such series shall no longer be registered or in
good standing under the Exchange Act, or other applicable statute
or regulation and a successor Depositary for such series is not
appointed by the Company within 90 days after the Company
receives such notice or becomes aware of such condition, as the
case may be or (ii) there shall have occurred and be continuing
after any applicable grace periods an Event of Default with
respect to the Securities for a series, then in each such case,
this Section 311 shall no longer be applicable to the Securities
of such series and the Company will execute, and subject to
Section 305 hereof, the Trustee will authenticate and deliver
Securities of such series in definitive registered form without
coupons, in authorized denominations, and in an aggregate
principal amount equal to the principal amount of the Global
Securities of such series in exchange for such Global Securities.
In addition, the Company may at any time determine that the
Securities of any series shall no longer be represented by Global
Securities and that the provisions of this Section 311 shall no
longer apply to the Securities of such series.  In such event the
Company will execute and subject to Section 305 hereof, the
Trustee, upon receipt of an Officers' Certificate evidencing such
determination by the Company, will authenticate and deliver
Securities of such series in definitive registered form without
coupons, in authorized denominations, and in an aggregate
principal amount equal to the principal amount of the Global
Securities of such series in exchange for such Global Securities.
Upon the exchange of the Global Securities for such Securities in
definitive registered form without coupons, in authorized
denominations, the Global Securities shall be canceled by the
Trustee.  Such Securities in definitive registered form issued in
exchange for the Global Securities pursuant to this Section 311,
shall be registered in such names and in such authorized
denominations as the Depositary, pursuant to the instructions
from its direct or indirect participants or otherwise, shall
instruct the Trustee.  The Trustee shall deliver Securities to
the Depositary for delivery to the persons in whose names such
Securities are so registered.

SECTION 312.  Payment of Securities.

          The Trustee shall receive the Senior Note Mortgage
Bonds from the Company as provided in this Indenture and shall
hold the Senior Note Mortgage Bonds, and any and all sums payable
thereon or with respect thereto or realized therefrom, in trust
for the benefit of the Holders of the Securities, as herein
provided.  Subject to Article Five hereof, all payments made by
the Company to the Trustee on a series of Senior Note Mortgage
Bonds shall be applied by the Trustee to pay, when due, principal
of, premium, if any, and interest on the related series of
Securities and, to the extent so applied, shall satisfy the
Company's obligations on such Securities.  Notwithstanding the
foregoing, the Company's obligation to make payments of principal
of, premium, if any, and interest on any series of Senior Note
Mortgage Bonds shall be fully satisfied by making timely payments
of principal of, premium, if any, and interest on the related
series of Securities.

          (2)  the Company has paid or caused to be paid all
     other sums payable hereunder by the Company; and

          (3)  the Company has delivered to the Trustee an
     Officers' Certificate and an Opinion of Counsel, each
     stating that all conditions precedent herein provided for

Securities and this Indenture, to the payment, to the persons
entitled thereto, of the principal (and premium, if any) and
interest, if any, for whose payment such money has been deposited

written certification thereof delivered to the Trustee, are then
in excess of the amount thereof which then would have been
required to be deposited for the purpose for which such U.S.
Government Obligations or money was deposited or received.  This
provision shall not authorize the sale by the Trustee of any U.S.
Government Obligations held under this Indenture.

     to receive, from the trust funds described in subparagraph

     accordance with their terms will provide not later than one
     day before the due date of any payment referred to in clause
     (x) or (y) of this subparagraph (e) money in an amount or
     (B) a combination thereof, in each case sufficient, in the

          (f)  the Company has delivered to the Trustee an
     Opinion of Counsel to the effect that such provision would
     not cause any Outstanding Securities of such series then
     listed on any national securities exchange to be delisted as
     a result thereof;

          (g)  no Event of Default or event which with notice or
     lapse of time would become an Event of Default (including by

     date of such deposit or during the period ending on the 91st
     day after such date;

          (h)  the Company has delivered to the Trustee an
     unqualified opinion, in form and substance reasonably
     acceptable to the Trustee, of independent counsel of
     national standing selected by the Company and satisfactory
     to the Trustee to the effect that (i) Holders of the
     Securities will not recognize income, gain or loss for
     Federal income tax purposes as a result of the deposit,
     defeasance and discharge, which opinion shall be based on a
     change in law or a ruling by the U.S. Internal Revenue

     registered as, an investment company under the Investment

     Board Resolution delivered to the Trustee on or prior to the
     date of deposit of such money or U.S. Government
     Obligations, and such Board Resolution shall be accompanied
     by an irrevocable Company Request that the Trustee give
     notice of such redemption in the name and at the expense of
     the Company not less than 30 nor more than 60 days prior to
     such Redemption Date in accordance with Section 1104 hereof;

SECTION 404.  Release of Related Series of Senior Note
              Mortgage Bonds.

          (a)  If any series of Securities are deemed paid and
discharged pursuant to this Article Four, the obligation of the
Company to make payment with respect to the principal of and
premium, if any, and interest on the related series of Senior
Note Mortgage Bonds shall be satisfied and discharged, and the
related series of Senior Note Mortgage Bonds shall cease to
secure the Securities in any manner.

to any lien, benefit or security under this Indenture, the
obligation of the Company to make payment with respect to
principal of and premium, if any, and interest on a principal
amount of the related series of Senior Note Mortgage Bonds equal

discharged and such portion of the principal amount of such
Senior Note Mortgage Bonds shall cease to secure the Securities
in any manner.

          (c)  Upon the satisfaction and discharge of this
Indenture, the Trustee shall at the request of the Company return
to the Company all Senior Note Mortgage Bonds and all other
property and money held by it under this Indenture and determined
by it from time to time in accordance with the certification
pursuant to Section 402(c) hereof to be in excess of the amount
required to be held under such Section 402 hereof.

     Section 501 specifically dealt with or which has expressly
     been included in this Indenture solely for the benefit of
     any series of Securities other than that series), and
     continuance of such default or breach for a period of 90
     days after there has been given, by registered or certified

     is a "Notice of Default" hereunder; or

          (5)  prior to the Release Date, a "default" as defined
     in the First Mortgage Indenture has occurred and is
     continuing, and the First Mortgage Trustee, the Company or
     Holders of at least 33% in aggregate principal amount of the
     Securities at the time outstanding shall have given written
     notice thereof to the Trustee; or

          (6)  the entry by a court having jurisdiction in the
     premises of (A) a decree or order for relief in respect of
     the Company in an involuntary case or proceeding under any
     applicable Federal or State bankruptcy, insolvency or other
     similar law or (B) a decree or order appointing a custodian,

     part of its property, or ordering the winding up or
     liquidation of its affairs, and the continuance of any such
     decree or order for relief or any such other decree or order
     unstayed and in effect for a period of 90 consecutive days;
     or

          (7)  the commencement by the Company of a voluntary
     case or proceeding under any applicable Federal or State
     bankruptcy, insolvency or other similar law or of any other
     case or proceeding to be adjudicated a bankrupt or

     order for relief in respect of the Company in an involuntary
     case or proceeding under any applicable Federal or State
     bankruptcy, insolvency or other similar law or to the
     commencement of any bankruptcy or insolvency case or
     proceeding against it, or the filing by it of a petition or
     answer or consent seeking relief under any applicable
     Federal or State law, or the consent by it to the filing of
     such petition or to the appointment of or taking possession
     by a custodian, receiver, liquidator, assignee, trustee,
     sequestrator or similar official of the Company or of any
     substantial part of its property, or the making by it of an
     assignment for the benefit of creditors, or the taking of
     corporate action by the Company in furtherance of any such
     action; or

          (8)  any other Event of Default provided in the
     supplemental indenture or provided in or pursuant to the
     Board Resolution under which such series of Securities is
     issued or in the form of Security for such series.

SECTION 502.  Acceleration of Maturity; Rescission and Annulment.

          If an Event of Default with respect to Securities of
any series at the time Outstanding described in paragraph (1),
(2), (3), (4), (5) or (8) of Section 501 hereof occurs and is
continuing, then in every such case the Trustee or the Holders of
not less than 33% in aggregate principal amount of the
Outstanding Securities of that series may declare the principal
amount (or, if any of the Securities of that series are Original
Issue Discount Securities, such portion of the principal amount
of such Securities as may be specified in the terms thereof) of
all of the Securities of that series to be due and payable
immediately, by a notice in writing to the Company (and to the
Trustee if given by Holders), and upon any such declaration such
principal amount (or specified amount) shall become immediately
due and payable upon the date which is 10 days after the date of
such notice.

          If an Event of Default described in paragraph (6) or
(7) of Section 501 hereof occurs and is continuing, then and in
every such case, the principal amount (or, if any Securities are
Original Issue Discount Securities, such portion of the principal
amount as may be specified in the terms thereof) of all the
Securities shall, without any notice to the Company or any other
act on the part of the Trustee or any Holder of the Securities,
become and be immediately due and payable.

          Upon the Securities being declared to be or becoming
due and payable, the Trustee can immediately file with the First
Mortgage Trustee a written demand for redemption of all Senior
Note Mortgage Bonds pursuant to the applicable provisions of the
supplemental indenture to the First Mortgage Indenture.

          At any time after such a declaration of acceleration
with respect to Securities of any series has been made and before
a judgment or decree for payment of the money due has been
obtained by the Trustee as hereinafter in this Article provided
and prior to the mailing to the Trustee by the First Mortgage
Trustee of a firm, valid and unconditional notice to the Trustee
of the acceleration of all of the first mortgage bonds issued and
outstanding under the First Mortgage Indenture, the Holders of a
majority in principal amount of the Outstanding Securities of
that series, by written notice to the Company and the Trustee,
may rescind and annul such declaration and its consequences
(including if given the written demand for redemption of all
Senior Note Mortgage Bonds) if

          (1)  the Company has paid or deposited with the Trustee
     a sum sufficient to pay

                    (A)  all overdue interest, if any, on all
          Securities of that series,

                    (B)  the principal of (and premium, if any,
          on) any Securities of that series which have become due
          otherwise than by such declaration of acceleration and
          interest thereon at the rate or rates prescribed
          therefor in such Securities,

                    (C)  to the extent that payment of such
          interest is lawful, interest upon any overdue interest
          at the rate or rates prescribed therefor in such
          Securities, and

                    (D)  all sums paid or advanced by the Trustee
          hereunder and the reasonable compensation, expenses,
          disbursements and advances of the Trustee, its agents
          and counsel; and

          (2)  all Events of Default with respect to Securities
     of that series, other than the non-payment of the principal
     of and accrued interest on Securities of that series which
     have become due solely by such declaration of acceleration,
     have been cured or waived as provided in Section 513 hereof
     (including any defaults under the First Mortgage Indenture,
     as evidenced by notice thereof from the First Mortgage
     Trustee to the Trustee).

No such rescission shall affect any subsequent default or impair
any right consequent thereon.

          For all purposes under this Indenture, if a portion of
the principal of any Original Issue Discount Securities shall
have been accelerated and declared due and payable pursuant to
the provisions hereof, then, from and after such declaration,
unless such declaration has been rescinded and annulled, the
principal amount of such Original Issue Discount Securities shall
be deemed, for all purposes hereunder, to be such portion of the
principal thereof as shall be due and payable as a result of such
acceleration, and payment of such portion of the principal
thereof as shall be due and payable as a result of such
acceleration, together with interest, if any, thereon and all
other amounts owing thereunder, shall constitute payment in full
of such Original Issue Discount Securities.

SECTION 503.  Collection of Indebtedness and Suits for Enforcement 
                by Trustee.

          The Company covenants that if

          (1)  default is made in the payment of any interest on
     any Security when such interest becomes due and payable and
     such default continues for a period of 30 days, or

          (2)  default is made in the payment of the principal of
     (or premium, if any, on) any Security at the Maturity
     thereof,

the Company will, upon written demand of the Trustee, pay to it,
for the benefit of the Holders of such Securities, the whole
amount then due and payable on such Securities for principal (and
premium, if any) and interest, if any, and, to the extent that
payment of such interest shall be legally enforceable, interest
on any overdue principal (and premium, if any) and on any overdue
interest, at the rate or rates prescribed therefor in such
Securities, and, in addition thereto, such further amount as
shall be sufficient to cover the costs and expenses of
collection, including the reasonable compensation, expenses,
disbursements and advances of the Trustee, its agents and
counsel.

          If the Company fails to pay such amounts forthwith upon
such demand, the Trustee, in its own name and as trustee of an
express trust, may institute a judicial proceeding for the
collection of the sums so due and unpaid (including, prior to the
Release Date, to exercise any rights to that end it may have as a
holder of Senior Note Mortgage Bonds), may prosecute such
proceeding to judgment or final decree and may enforce the same
against the Company or any other obligor upon such Securities and
collect the moneys adjudged or decreed to be payable in the
manner provided by law out of the property of the Company or any
other obligor upon such Securities, wherever situated.

          If any Event of Default with respect to Securities of
any series occurs and is continuing, the Trustee may in its
discretion proceed to protect and enforce its rights (including,
prior to the Release Date, its rights as holder of the Senior
Note Mortgage Bonds) and the rights of the Holders of Securities
of such series by such appropriate judicial proceedings as the
Trustee shall deem most effectual to protect and enforce any such
rights.

          The Trustee shall not be required to take notice or be
deemed to have notice of any Event of Default other than pursuant
to paragraphs (1), (2) or (3) of Section 501 of this Indenture,
unless the Trustee shall be specifically notified in writing of
such default by the Company, or by the Holders of a majority in
aggregate principal amount of Outstanding Securities.

SECTION 504.  Trustee May File Proofs of Claim.

          In case of the pendency of any receivership,
insolvency, liquidation, bankruptcy, reorganization, arrangement,
adjustment, composition or other judicial proceeding relative to
the Company or any other obligor upon the Securities or the
property of the Company or of such other obligor or their
creditors, the Trustee (irrespective of whether the principal of
the Securities shall then be due and payable as therein expressed
or by declaration or otherwise and irrespective of whether the
Trustee shall have made any demand on the Company for the payment
of overdue principal or interest) shall be entitled and
empowered, by intervention in such proceeding or otherwise,

          (i)  to file and prove a claim for the whole amount of
     principal (and premium, if any) and interest owing and
     unpaid in respect of the Securities and to file such other
     papers or documents as may be necessary or advisable in
     order to have the claims of the Trustee (including, prior to
     the Release Date, any claims of the Trustee as holder of
     Senior Note Mortgage Bonds and including any claim for the
     reasonable compensation, expenses, disbursements and
     advances of the Trustee, its agents and counsel) and of the
     Holders allowed in such judicial proceeding, and

         (ii)  to collect and receive any moneys or other
     property payable or deliverable on any such claims and to
     distribute the same;

and any custodian, receiver, assignee, trustee, liquidator,
sequestrator or other similar official in any such judicial
proceeding is hereby authorized by each Holder to make such
payments to the Trustee and, in the event that the Trustee shall
consent to the making of such payments directly to the Holders,
to pay to the Trustee any amount due it for the reasonable
compensation, expenses, disbursements and advances of the
Trustee, its agents and counsel, and any other amounts due the
Trustee under Section 607 hereof.

          Nothing herein contained shall be deemed to authorize
the Trustee to authorize or consent to or accept or adopt on
behalf of any Holder any plan of reorganization, arrangement,
adjustment or composition affecting the Securities or the rights
of any Holder thereof or to authorize the Trustee to vote in
respect of the claim of any Holder in any such proceeding.

SECTION 505.  Trustee May Enforce Claims Without Possession of
              Securities.

          All rights of action and claims under this Indenture or
the Securities may be prosecuted and enforced by the Trustee,
including, prior to the Release Date, its rights as holder of the
Senior Note Mortgage Bonds without the possession of any of the
Securities or the production thereof in any proceeding relating
thereto, and any such proceeding instituted by the Trustee shall
be brought in its own name as trustee of an express trust, and
any recovery of judgment shall, after provision for the payment
of the reasonable compensation, expenses, disbursements and
advances of the Trustee, its agents and counsel, be for the
ratable benefit of the Holders of the Securities in respect of
which such judgment has been recovered.

SECTION 506.  Application of Money Collected.

          Any money collected by the Trustee pursuant to this
Article shall be applied in the following order with respect to
the Securities of any series, at the date or dates fixed by the
Trustee and, in case of the distribution of such money on account
of principal (or premium, if any) or interest, upon presentation
of the Securities and the notation thereon of the payment if only
partially paid and upon surrender thereof if fully paid:

          FIRST:  To the payment of all amounts due the Trustee
     under Section 607 hereof;

          SECOND:  In case the principal and premium, if any, of
     the Securities of such series in respect of which moneys
     have been collected shall not have become and be then due
     and payable, to the payment of interest, if any, on the
     Securities of such series in default in the order of the
     maturity of the installments of such interest, with interest
     (to the extent that such interest has been collected by the
     Trustee and to the extent permitted by law) upon the overdue
     installments of interest at the rate prescribed therefor in
     such Securities, such payments to be made ratably to the
     Persons entitled thereto, without discrimination or
     preference;

          THIRD:  In case the principal or premium, if any, of
     the Securities of such series in respect of which moneys
     have been collected shall have become and shall be then due
     and payable, to the payment of the whole amount then owing
     and unpaid upon all the Securities of such series for
     principal and premium, if any, and interest, if any, with
     interest upon the overdue principal and premium, if any, and
     (to the extent that such interest has been collected by the
     Trustee and to the extent permitted by law) upon overdue
     installments of interest at the rate prescribed therefor in
     the Securities of such series; and in case such moneys shall
     be insufficient to pay in full the whole amount so due and
     unpaid upon the Securities of such series, then to the
     payment of such principal and any premium and interest,
     without preference or priority of principal over interest,
     or of interest over principal or premium, or of any
     installment of interest over any other installment of
     interest, or of any Security of such series over any other
     Security of such series, ratably to the aggregate of such
     principal and any premium and accrued and unpaid interest;
     and

          FOURTH:  To the payment of the remainder, if any, to
     the Company or any other Person lawfully entitled thereto.

SECTION 507.  Limitation on Suits.

          No Holder of any Security of any series shall have any
right to institute any proceeding, judicial or otherwise, with
respect to this Indenture, or for the appointment of a receiver
or trustee, or for any other remedy hereunder, unless

          (1)  such Holder has previously given written notice to
     the Trustee of a continuing Event of Default with respect to
     the Securities of that series;

          (2)  the Holders of not less than 33% in principal
     amount of the Outstanding Securities of that series shall
     have made written request to the Trustee to institute
     proceedings in respect of such Event of Default in its own
     name as Trustee hereunder;

          (3)  such Holder or Holders have offered to the Trustee
     reasonable indemnity against the costs, expenses and
     liabilities to be incurred in compliance with such request;

          (4)  the Trustee for 60 days after its receipt of such
     notice, request and offer of indemnity has failed to
     institute any such proceeding; and

          (5)  no direction inconsistent with such written
     request has been given to the Trustee during such 60-day
     period by the Holders of a majority in principal amount of
     the Outstanding Securities of that series;

it being understood and intended that no one or more of such
Holders shall have any right in any manner whatever by virtue of,
or by availing of, any provision of this Indenture to affect,
disturb or prejudice the rights of any other of such Holders, or
to obtain or to seek to obtain priority or preference over any
other of such Holders or to enforce any right under this
Indenture, except in the manner herein provided and for the equal
and ratable benefit of all such Holders.

SECTION 508.  Unconditional Right of Holders to Receive
              Principal, Premium and Interest.

          Notwithstanding any other provision in this Indenture,
the Holder of any Security shall have the right, which is
absolute and unconditional, to receive payment of the principal
of (and premium, if any) and (subject to Section 307 hereof)
interest, if any, on such Security on the Stated Maturity or
Maturities expressed in such Security (or, in the case of
redemption, on the Redemption Date) and to institute suit for the
enforcement of any such payment, and such rights shall not be
impaired without the consent of such Holder.

SECTION 509.  Restoration of Rights and Remedies.

          If the Trustee or any Holder has instituted any
proceeding to enforce any right or remedy under this Indenture
and such proceeding has been discontinued or abandoned for any
reason, or has been determined adversely to the Trustee or to
such Holder, then and in every such case, subject to any
determination in such proceeding, the Company, the Trustee and
the Holders shall be restored severally and respectively to their
former positions hereunder and thereafter all rights and remedies
of the Trustee and the Holders shall continue as though no such
proceeding had been instituted.

SECTION 510.  Rights and Remedies Cumulative.

          Except as otherwise provided with respect to the
replacement or payment of mutilated, destroyed, lost or stolen
Securities in the last paragraph of Section 306 hereof, no right
or remedy herein conferred upon or reserved to the Trustee or to
the Holders is intended to be exclusive of any other right or
remedy, and every right and remedy shall, to the extent permitted
by law, be cumulative and in addition to every other right and
remedy given hereunder or now or hereafter existing at law or in
equity or otherwise.  The assertion or employment of any right or
remedy hereunder, or otherwise, shall not prevent the concurrent
assertion or employment of any other appropriate right or remedy.

SECTION 511.  Delay or Omission Not Waiver.

          No delay or omission of the Trustee or of any Holder of
any Securities to exercise any right or remedy accruing upon any
Event of Default shall impair any such right or remedy or
constitute a waiver of any such Event of Default or an
acquiescence therein.  Every right and remedy given by this
Article or by law to the Trustee or to the Holders may be
exercised from time to time, and as often as may be deemed
expedient, by the Trustee or by the Holders, as the case may be.

SECTION 512.  Control by Holders.

          The Holders of a majority in principal amount of the
Outstanding Securities of any series shall have the right to
direct the time, method and place of conducting any proceeding
for any remedy available to the Trustee, or exercising any trust
or power conferred on the Trustee, with respect to the Securities
of such series, provided that

          (1)  such direction shall not be in conflict with any
     rule of law or with this Indenture,

          (2)  the Trustee may take any other action deemed
     proper by the Trustee which is not inconsistent with such
     direction, and

          (3)  the Trustee shall not determine that the action so
     directed would be unjustly prejudicial to Holders not taking
     part in such action.

SECTION 513.  Waiver of Past Defaults.

          The Holders of not less than a majority in aggregate
principal amount of the Outstanding Securities of any series may
on behalf of the Holders of all the Securities of such series
waive any past default hereunder with respect to such series and
its consequences, except a default

          (1)  in the payment of the principal of (or premium, if
     any) or interest, if any, on any Security of such series, or

          (2)  in respect of a covenant or provision hereof which
     under Article Nine cannot be modified or amended without the
     consent of the Holder of each Outstanding Security of such
     series affected.

          Upon any such waiver, such default shall cease to
exist, and any Event of Default arising therefrom shall be deemed
to have been cured, for every purpose of this Indenture; but no
such waiver shall extend to any subsequent or other default or
impair any right consequent thereon.

SECTION 514.  Undertaking for Costs.

          All parties to this Indenture agree, and each Holder of
any Security by his acceptance thereof shall be deemed to have
agreed, that any court may in its discretion require, in any suit
for the enforcement of any right or remedy under this Indenture,
or in any suit against the Trustee for any action taken or
omitted by it as Trustee, the filing by any party litigant in
such suit of an undertaking to pay the costs of such suit, and
that such court may in its discretion assess reasonable costs,
including reasonable attorneys' fees, against any party litigant
in such suit, having due regard to the merits and good faith of
the claims or defenses made by such party litigant; but the
provisions of this Section 514 shall not apply to any suit
instituted by the Trustee, to any suit instituted by any Holder,
or group of Holders, holding in the aggregate more than 10% in
principal amount of the Outstanding Securities of any series, or
to any suit instituted by any Holder for the enforcement of the
payment of the principal of (or premium, if any) or interest, if
any, on any Security on or after the Stated Maturity or
Maturities expressed in such Security (or, in the case of
redemption, on or after the Redemption Date).


                          ARTICLE SIX

                          THE TRUSTEE

SECTION 601.  Certain Duties and Responsibilities.

          (a)  Except during the continuance of a default with
respect to the Securities of any series,

          (1)  the Trustee undertakes to perform such duties and
     only such duties as are specifically set forth in this
     Indenture, and no implied covenants or obligations shall be
     read into this Indenture against the Trustee; and

          (2)  in the absence of bad faith on its part, the
     Trustee may conclusively rely, as to the truth of the
     statements and the correctness of the opinions expressed
     therein, upon certificates or opinions furnished to the
     Trustee and conforming to the requirements of this
     Indenture; but in the case of any such certificates or
     opinions which by any provision hereof are specifically
     required to be furnished to the Trustee, the Trustee shall
     examine the same to determine whether or not they conform to
     the requirements of this Indenture.

          (b)  In case a default has occurred and is continuing,
the Trustee shall exercise such of the rights and powers vested
in it by this Indenture, and use the same degree of care and
skill in their exercise, as a prudent man would exercise or use
under the circumstances in the conduct of his own affairs.

          (c)  No provision of this Indenture shall be construed
to relieve the Trustee from liability for its own negligent
action, its own negligent failure to act, or its own wilful
misconduct, except that

          (1)  this Subsection shall not be construed to limit
     the effect of Subsection (a) of this Section 601;

          (2)  the Trustee shall not be liable for any error of
     judgment made in good faith by a Responsible Officer, unless
     it shall be proved that the Trustee was negligent in
     ascertaining the pertinent facts;

          (3)  the Trustee shall not be liable with respect to
     any action taken or omitted to be taken by it in good faith
     in accordance with the direction of the Holders of a
     majority in principal amount of the Outstanding Securities
     of any series, determined as provided in Section 512 hereof,
     relating to the time, method and place of conducting any
     proceeding for any remedy available to the Trustee, or
     exercising any trust or power conferred upon the Trustee,
     under this Indenture with respect to the Securities of such
     series; and

          (4)  no provision of this Indenture shall require the
     Trustee to expend or risk its own funds or otherwise incur
     any financial liability in the performance of any of its
     duties hereunder, or in the exercise of any of its rights or
     powers, if it shall have reasonable grounds for believing
     that repayment of such funds or adequate indemnity against
     such risk or liability is not reasonably assured to it.

          (d)  Whether or not therein expressly so provided,
every provision of this Indenture relating to the conduct or
affecting the liability of or affording protection to the Trustee
shall be subject to the provisions of this Section 601.  The
permissive right of the Trustee to do things enumerated in this
Indenture shall not be construed as a duty and it shall not be
answerable for other than its own negligent action, its own
negligent failure to act or its own willful misconduct.

SECTION 602.  Notice of Defaults.

          Within 90 days after the occurrence of any default
hereunder with respect to the Securities of any series, the
Trustee shall transmit by mail to all Holders of Securities of
such series, as their names and addresses appear in the Security
Register, notice of such default hereunder known to the Trustee,
unless such default shall have been cured or waived; provided,
however, that, except in the case of a default in the payment of
the principal of (or premium, if any) or interest, if any, on any
Security of such series or in the payment of any sinking fund
installment with respect to Securities of such series, the
Trustee shall be protected in withholding such notice if and so
long as the board of directors, the executive committee or a
trust committee of directors or Responsible Officers of the
Trustee in good faith determine that the withholding of such
notice is in the interest of the Holders of Securities of such
series; and provided, further, that in the case of any default of
the character specified in Section 501(4) hereof with respect to
Securities of such series, no such notice to Holders shall be
given until at least 30 days after the occurrence thereof.  For
the purpose of this Section 602, the term "default" means any
event which is, or after notice or lapse of time or both would
become, an Event of Default with respect to Securities of such
series.

SECTION 603.  Certain Rights of Trustee.

          Subject to the provisions of Section 601 hereof:

          (a)  the Trustee may rely and shall be fully protected
in acting or refraining from acting upon any resolution,
certificate, statement, instrument, opinion, report, notice,
request, direction, consent, order, bond, debenture, note, other
evidence of indebtedness or other paper or document believed by
it to be genuine and to have been signed or presented by the
proper party or parties;

part, rely upon an Officers' Certificate;

          (d)  the Trustee may consult with counsel and the
written advice of such counsel or any Opinion of Counsel shall be

or risk its own funds or to exercise, at the request or direction
of any of the Holders, any of the rights or powers vested in it
by this Indenture pursuant to this Indenture, unless such Holders
shall have offered to the Trustee reasonable security or
indemnity against the costs, expenses and liabilities which might
be incurred by it in compliance with such request or direction;

          (f)  the Trustee shall not be bound to make any
investigation into the facts or matters stated in any resolution,
certificate, statement, instrument, opinion, report, notice,

Trustee, in its discretion, may make such further inquiry or
investigation into such facts or matters as it may see fit, and,
if the Trustee shall determine to make such further inquiry or
investigation, it shall be entitled upon reasonable request to
examine the books, records and premises of the Company,
personally or by agent or attorney; and

          (g)  the Trustee may execute any of the trusts or
powers hereunder or perform any duties hereunder either directly
or by or through agents or attorneys and the Trustee shall not be
responsible for any misconduct or negligence on the part of any
agent or attorney appointed with due care by it hereunder.

SECTION 604.  Not Responsible for Recitals or Issuance of
              Securities.

          The recitals contained herein and in the Securities,
except the Trustee's certificates of authentication, shall be
taken as the statements of the Company, and neither the Trustee
nor any Authenticating Agent assumes any responsibility for their
correctness.  The Trustee makes no representations as to the
validity or sufficiency of this Indenture or of the Securities.
Neither the Trustee nor any Authenticating Agent shall be
accountable for the use or application by the Company of
Securities or the proceeds thereof.  The Trustee shall not be
responsible for doing or performing any thing or act which the
Company shall have covenanted to do or perform, or for any
compliance with any covenant by the Company, nor shall the
Trustee be bound to ascertain or inquire as to the performance of
any covenant, condition or agreement by the Company, but it may
require full information and advice in regard to any of the
foregoing.

SECTION 605.  May Hold Securities.

          The Trustee, any Authenticating Agent, any Paying
Agent, any Security Registrar or any other agent of the Company,
in its individual or any other capacity, may become the owner or
pledgee of Securities and, subject to Sections 608 and 613
hereof, may otherwise deal with the Company with the same rights
it would have if it were not Trustee, Authenticating Agent,
Paying Agent, Security Registrar or such other agent.

SECTION 606.  Money Held in Trust.

          Money held by the Trustee in trust hereunder need not
be segregated from other funds except to the extent required by

money received by it hereunder except as otherwise agreed with
the Company.

SECTION 607.  Compensation and Reimbursement.

          The Company agrees

          (1)  to pay to the Trustee from time to time such
     compensation as is agreed upon in writing, or, if no such
     agreement exists, reasonable compensation for all services
     rendered by it hereunder (which compensation shall not be
     limited by any provision of law in regard to the
     compensation of a trustee of an express trust), and shall
     have a lien therefor on any and all funds at any time held
     by it under this Indenture for such compensation;

          (2)  except as otherwise expressly provided herein, to
     reimburse the Trustee upon its request for all reasonable
     expenses, disbursements and advances incurred or made by the
     Trustee in accordance with any provision of this Indenture
     (including the reasonable compensation and the expenses and
     disbursements of its agents and counsel, which compensation,
     expenses and disbursements shall be set forth in sufficient
     detail), and shall have a lien therefor on any and all funds
     at any time held by it under this Indenture for such
     expenses and disbursements, except any such expense,
     disbursement or advance as may be attributable to its
     negligence or bad faith; and

          (3)  to indemnify the Trustee for, and to hold it
     harmless against, any loss, liability or expense incurred
     without negligence or bad faith on its part, arising out of
     or in connection with the acceptance or administration of
     the trust or trusts hereunder, including the costs and
     expenses of defending itself against any claim or liability
     in connection with the exercise or performance of any of its
     powers or duties hereunder.

SECTION 608.  Disqualification; Conflicting Interests.

          If the Trustee has or shall acquire a conflicting
interest within the meaning of the Trust Indenture Act, the
Trustee shall either eliminate such interest or resign, to the
extent and in the manner provided by, and subject to the
provisions of, the Trust Indenture Act and this Indenture
provided that, to the extent permitted by law, Liberty Bank and
Trust Company of Tulsa, National Association shall not be deemed
to have a conflicting interest for purposes of Section 310(b) of
the Trust Indenture Act because of its capacity as trustee under
the First Mortgage Indenture.  Nothing in this Indenture shall be
deemed to prohibit the Trustee or the Company from making any
application permitted pursuant to Section 310(b) of the Trust
Indenture Act.

SECTION 609.  Corporate Trustee Required; Eligibility.

          There shall at all times be a Trustee hereunder which
shall be eligible to act as trustee under the Trust Indenture Act
and which shall have a combined capital and surplus of at least
$50,000,000.  If the Trustee does not have an office in The City
of New York, the Trustee may appoint an agent in The City of New
York reasonably acceptable to the Company to conduct any
activities which the Trustee may be required under this Indenture
to conduct in The City of New York.  If the Trustee does not have
an office in The City of New York or has not appointed an agent
in The City of New York, the Trustee shall be a participant in
The Depository Trust Company and FAST distribution systems.  If
such corporation publishes reports of condition at least
annually, pursuant to law or to the requirements of a Federal,
State, or District of Columbia supervising or examining
authority, then for the purposes of this Section 609, the
combined capital and surplus of such corporation shall be deemed
to be its combined capital and surplus as set forth in its most
recent report of condition so published.  If at any time the
Trustee shall cease to be eligible in accordance with the
provisions of this Section 609, the Trustee shall resign
immediately in the manner and with the effect hereinafter
specified in this Article.

SECTION 610.   Resignation and Removal; Appointment of Successor
               Trustee.

          (a)  No resignation or removal of the Trustee and no
appointment of a successor Trustee pursuant to this Article shall
become effective until the acceptance of appointment by the
successor Trustee in accordance with the applicable requirements
of Section 611 hereof.

          (b)  The Trustee may resign at any time with respect to
the Securities of one or more series by giving written notice
thereof to the Company.  If the instrument of acceptance by a
successor Trustee required by Section 611 hereof shall not have
been delivered to the Trustee within 30 days after the giving of
such notice of resignation, the resigning Trustee may petition
any court of competent jurisdiction for the appointment of a
successor Trustee with respect to the Securities of such series.

          (c)  The Trustee may be removed at any time with
respect to the Securities of any series by Act of the Holders of
a majority in principal amount of the Outstanding Securities of
such series, delivered to the Trustee and to the Company.

          (d)  If at any time:

          (1)  the Trustee shall fail to comply with Section
     310(b) of the Trust Indenture Act pursuant to Section 608
     hereof with respect to any series of Securities after
     written request therefor by the Company or by any Holder who
     has been a bona fide Holder of a Security for at least six
     months, or

          (2)  the Trustee shall cease to be eligible under
     Section 609 hereof and shall fail to resign after written
     request therefor by the Company or by any such Holder, or

          (3)  the Trustee shall become incapable of acting or
     shall be adjudged a bankrupt or insolvent or a receiver of
     the Trustee or of its property shall be appointed or any
     public officer shall take charge or control of the Trustee
     or of its property or affairs for the purpose of
     rehabilitation, conservation or liquidation,

then, in any such case, (i) the Company by a Board Resolution may
remove the Trustee with respect to all Securities, or (ii)
subject to Section 514 hereof, any Holder who has been a bona
fide Holder of a Security for at least six months may, on behalf
of himself and all others similarly situated, petition any court
of competent jurisdiction for the removal of the Trustee with
respect to all Securities and the appointment of a successor
Trustee or Trustees.

          (e)  If the Trustee shall resign, be removed or become
incapable of acting, or if a vacancy shall occur in the office of
Trustee for any cause, with respect to the Securities of one or
more series, the Company, by a Board Resolution, shall promptly
appoint a successor Trustee or Trustees with respect to the
Securities of that or those series (it being understood that any
such successor Trustee may be appointed with respect to the
Securities of one or more or all of such series and that at any
time there shall be only one Trustee with respect to the
Securities of any particular series) and shall comply with the
applicable requirements of Section 611 hereof.  If, within one
year after such resignation, removal or incapability, or the
occurrence of such vacancy, a successor Trustee with respect to
the Securities of any series shall be appointed by Act of the
Holders of a majority in principal amount of the Outstanding
Securities of such series delivered to the Company and the
retiring Trustee, the successor Trustee so appointed shall,
forthwith upon its acceptance of such appointment in accordance
with the applicable requirements of Section 611 hereof, become the
successor Trustee with respect to the Securities of such series and 
to that extent supersede the successor Trustee appointed by the Company. 
If no successor Trustee with respect to the Securities of any series 
shall have been so appointed by the Company or the Holders and accepted
appointment in the manner required by Section 611 hereof, any
Holder who has been a bona fide Holder of a Security of such
series for at least six months may, on behalf of himself and all
others similarly situated, petition any court of competent
jurisdiction for the appointment of a successor Trustee with
respect to the Securities of such series.

          (f)  The Company shall give notice of each resignation
and each removal of the Trustee with respect to the Securities of
any series and each appointment of a successor Trustee with
respect to the Securities of any series by mailing written notice
of such event by first-class mail, postage prepaid, to all
Holders of Securities of such series as their names and addresses
appear in the Security Register.  Each notice shall include the
name of the successor Trustee with respect to the Securities of
such series and the address of its Corporate Trust Office.

SECTION 611.  Acceptance of Appointment by Successor.

          (a)  In case of the appointment hereunder of a
successor Trustee with respect to all Securities, every such
successor Trustee so appointed shall execute, acknowledge and
deliver to the Company and to the retiring Trustee an instrument
accepting such appointment, and thereupon the resignation or
removal of the retiring Trustee shall become effective and such
successor Trustee, without any further act, deed or conveyance,
shall become vested with all the rights, powers, trusts and
duties of the retiring Trustee; but, on the request of the
Company or the successor Trustee, such retiring Trustee shall,
upon payment of its charges, execute and deliver an instrument
transferring to such successor Trustee all the rights, powers and
trusts of the retiring Trustee and shall duly assign, transfer
and deliver to such successor Trustee all property and money held
by such retiring Trustee hereunder (including all right, title,
and interest in the Senior Note Mortgage Bonds).

          (b)  In case of the appointment hereunder of a
successor Trustee with respect to the Securities of one or more
(but not all) series, the Company, the retiring Trustee and each
successor Trustee with respect to the Securities of one or more
series shall execute and deliver an indenture supplemental hereto
wherein each successor Trustee shall accept such appointment and
which (1) shall contain such provisions as shall be necessary or
desirable to transfer and confirm to, and to vest in, each
successor Trustee all the rights, powers, trusts and duties of
the retiring Trustee with respect to the Securities of that or
those series to which the appointment of such successor Trustee
relates, (2) if the retiring Trustee is not retiring with respect
to all Securities, shall contain such provisions as shall be
deemed necessary or desirable to confirm that all the rights,
powers, trusts and duties of the retiring Trustee with respect to
the Securities of that or those series as to which the retiring
Trustee is not retiring shall continue to be vested in the
retiring Trustee, and (3) shall add to or change any of the
provisions of this Indenture as shall be necessary to provide for
or facilitate the administration of the trusts hereunder by more
than one Trustee, it being understood that nothing herein or in
such supplemental indenture shall constitute such Trustees co-trustees
of the same trust and that each such Trustee shall be trustee of a trust
or trusts hereunder separate and apart from any trust or trusts
hereunder administered by any other such Trustee; and upon the
execution and delivery of such supplemental indenture the
resignation or removal of the retiring Trustee shall become
effective to the extent provided therein and each such successor
Trustee, without any further act, deed or conveyance, shall
become vested with all the rights, powers, trusts and duties of
the retiring Trustee with respect to the Securities of that or
those series to which the appointment of such successor Trustee
relates; but, on request of the Company or any successor trustee,
such retiring Trustee shall duly assign, transfer and deliver to
such successor Trustee all property and money held by such
retiring Trustee hereunder with respect to the Securities of that
or those series to which the appointment of such successor
Trustee relates.

          (c)  Upon request of any such successor Trustee, the
Company shall execute any and all instruments for more fully and
certainly vesting in and confirming to such successor Trustee all
such rights, powers and trusts referred to in paragraph (a) or
(b) of this Section 611, as the case may be.

          (d)  No successor Trustee shall accept its appointment
unless at the time of such acceptance such successor Trustee
shall be qualified and eligible under this Article.

SECTION 612.  Merger, Conversion, Consolidation or Succession to
              Business.

          Any corporation into which the Trustee may be merged or
converted or with which it may be consolidated, or any
corporation resulting from any merger, conversion or
consolidation to which the Trustee shall be a party, or any
corporation succeeding to all or substantially all the corporate
trust business of the Trustee, shall be the successor of the
Trustee hereunder, provided such corporation shall be otherwise
qualified and eligible under this Article, without the execution
or filing of any paper or any further act on the part of any of
the parties hereto.  In case any Securities shall have been
authenticated, but not delivered, by the Trustee then in office,
any successor by merger, conversion or consolidation to such
authenticating Trustee may adopt such authentication and deliver
the Securities so authenticated with the same effect as if such
successor Trustee had itself authenticated such Securities.

SECTION 613.  Preferential Collection of Claims Against Company.

          (a)  Subject to Subsection (b) of this Section 613, if
the Trustee shall be or shall become a creditor, directly or
indirectly, secured or unsecured, of the Company within three
months prior to a default, as defined in Subsection (c) of this
Section 613, or subsequent to such a default, then, unless and
until such default shall be cured, the Trustee shall set apart
and hold in a special account for the benefit of the Trustee
individually, the Holders of the Securities and the holders of
other indenture securities, as defined in Subsection (c) of this
Section 613:

          (1)  an amount equal to any and all reductions in the
     amount due and owing upon any claim as such creditor in
     respect of principal or interest, effected after the
     beginning of such three-month period and valid as against
     the Company and its other creditors, except any such
     reduction resulting from the receipt or disposition of any
     property described in paragraph (2) of this Subsection, or
     from the exercise of any right of set-off which the Trustee
     could have exercised if a petition in bankruptcy had been
     filed by or against the Company upon the date of such
     default; and

          (2)  all property received by the Trustee in respect of
     any claims as such creditor, either as security therefor, or
     in satisfaction or composition thereof, or otherwise, after
     the beginning of such three-month period, or an amount equal
     to the proceeds of any such property, if disposed of,
     subject, however, to the rights, if any, of the Company and
     its other creditors in such property or such proceeds.

          Nothing herein contained, however, shall affect the
right of the Trustee:

          (A)  to retain for its own account (i) payments made on
     account of any such claim by any Person (other than the
     Company) who is liable thereon, and (ii) the proceeds of the
     bona fide sale of any such claim by the Trustee to a third
     Person, and (iii) distributions made in cash, securities or
     other property in respect of claims filed against the
     Company in bankruptcy or receivership or in proceedings for
     reorganization pursuant to the Federal Bankruptcy Act or
     applicable State law;

          (B)  to realize, for its own account, upon any property
     held by it as security for any such claim, if such property
     was so held prior to the beginning of such three-month
     period;

          (C)  to realize, for its own account, but only to the
     extent of the claim hereinafter mentioned, upon any property
     held by it as security for any such claim, if such claim was
     created after the beginning of such three-month period and
     such property was received as security therefor
     simultaneously with the creation thereof, and if the Trustee
     shall sustain the burden of proving that at the time such
     property was so received the Trustee had no reasonable cause
     to believe that a default, as defined in Subsection (c) of
     this Section 613, would occur within three months; or

          (D)  to receive payment on any claim referred to in
     paragraph (B) or (C), against the release of any property
     held as security for such claim as provided in paragraph (B)
     or (C), as the case may be, to the extent of the fair value
     of such property.

          For the purposes of paragraphs (B), (C) and (D),
property substituted after the beginning of such three-month
period for property held as security at the time of such
substitution shall, to the extent of the fair value of the
property released, have the same status as the property released,
and, to the extent that any claim referred to in any of such
paragraphs is created in renewal of or in substitution for or for
the purpose of repaying or refunding any pre-existing claim of
the Trustee as such creditor, such claim shall have the same
status as such pre-existing claim.

          If the Trustee shall be required to account, the funds
and property held in such special account and the proceeds
thereof shall be apportioned among the Trustee, the Holders and
the holders of other indenture securities in such manner that the
Trustee, the Holders and the holders of other indenture
securities realize, as a result of payments from such special
account and payments of dividends on claims filed against the
Company in bankruptcy or receivership or in proceedings for
reorganization pursuant to the Federal Bankruptcy Act or
applicable State law, the same percentage of their respective
claims, figured before crediting to the claim of the Trustee
anything on account of the receipt by it from the Company of the
funds and property in such special account and before crediting
to the respective claims of the Trustee and the Holders and the
holders of other indenture securities dividends on claims filed
against the Company in bankruptcy or receivership or in
proceedings for reorganization pursuant to the Federal Bankruptcy
Act or applicable State law, but after crediting thereon receipts
on account of the indebtedness represented by their respective
claims from all sources other than from such dividends and from
the funds and property so held in such special account.  As used
in this paragraph, with respect to any claim, the term
"dividends" shall include any distribution with respect to such
claim, in bankruptcy or receivership or proceedings for
reorganization pursuant to the Federal Bankruptcy Act or
applicable State law, whether such distribution is made in cash,
securities or other property, but shall not include any such
distribution with respect to the secured portion, if any, of such
claim.  The court in which such bankruptcy, receivership or
proceedings for reorganization is pending shall have jurisdiction
(i) to apportion among the Trustee, the Holders and the holders
of other indenture securities, in accordance with the provisions
of this paragraph, the funds and property held in such special
account and proceeds thereof, or (ii) in lieu of such
apportionment, in whole or in part, to give to the provisions of
this paragraph due consideration in determining the fairness of
the distributions to be made to the Trustee and the Holders and
the holders of other indenture securities with respect to their
respective claims, in which event it shall not be necessary to
liquidate or to appraise the value of any securities or other
property held in such special account or as security for any such
claim, or to make a specific allocation of such distributions as
between the secured and unsecured portions of such claims, or
otherwise to apply the provisions of this paragraph as a
mathematical formula.

          Any Trustee which has resigned or been removed after
the beginning of such three-month period shall be subject to the
provisions of this Subsection as though such resignation or
removal had not occurred.  If any Trustee has resigned or been
removed prior to the beginning of such three-month period, it
shall be subject to the provisions of this Subsection if and only
if the following conditions exist:

          (i)  the receipt of property or reduction of claim,
     which would have given rise to the obligation to account, if
     such Trustee had continued as Trustee, occurred after the
     beginning of such three-month period; and

         (ii)  such receipt of property or reduction of claim
     occurred within three months after such resignation or
     removal.

          (b)  There shall be excluded from the operation of
Subsection (a) of this Section 613 a creditor relationship
arising from:

          (1)  the ownership or acquisition of securities issued
     under any indenture, or any security or securities having a
     maturity of one year or more at the time of acquisition by
     the Trustee;

          (2)  advances authorized by a receivership or
     bankruptcy court of competent jurisdiction or by this
     Indenture, for the purpose of preserving any property which
     shall at any time be subject to the lien of this Indenture
     or of discharging tax liens or other prior liens or
     encumbrances thereon, if notice of such advances and of the
     circumstances surrounding the making thereof is given to the
     Holders at the time and in the manner provided in this
     Indenture;

          (3)  disbursements made in the ordinary course of
     business in the capacity of trustee under an indenture,
     transfer agent, registrar, custodian, paying agent, fiscal
     agent or depository, or other similar capacity;

          (4)  an indebtedness created as a result of services
     rendered or premises rented; or an indebtedness created as a

SECTION 614.  Authenticating Agents.

          From time to time the Trustee, in its sole discretion,
may appoint one or more Authenticating Agents with respect to one
or more series of Securities with power to act on the Trustee's
behalf and subject to its direction in the authentication and
delivery of Securities of such series or in connection with
transfers and exchanges under Sections 304, 305, 306, and 1107
hereof as fully to all intents and purposes as though the
Authenticating Agent had been expressly authorized by those
Sections of this Indenture to authenticate and deliver Securities
of such series.  For all purposes of this Indenture, the
authentication and delivery of Securities by an Authenticating
Agent pursuant to this Section 614 shall be deemed to be
authentication and delivery of such Securities "by the Trustee".
Each such Authenticating Agent shall be acceptable to the Company
and shall at all times be a corporation organized and doing
business under the laws of the United States, any State thereof
or the District of Columbia, authorized under such laws to
exercise corporate trust powers, having a combined capital and
surplus of at least $50,000,000 and  subject to supervision or
examination by Federal, State or District of Columbia authority.
If such corporation publishes reports of condition at least
annually pursuant to law or the requirements of such authority,
then for the purposes of this Section 614 the combined capital
and surplus of such corporation shall be deemed to be its
combined capital and surplus as set forth in its most recent
report of condition so published.  If at any time an
Authenticating Agent shall cease to be eligible in accordance
with the provisions of this Section 614, such Authenticating
Agent shall resign immediately in the manner and with the effect
specified in this Section 614.

          Any corporation into which any Authenticating Agent may
be merged or with which it may be consolidated, or any
corporation resulting from any merger or consolidation or to
which any Authenticating Agent shall be a party, or any
corporation succeeding to the corporate trust business of any
Authenticating Agent, shall be the successor of the
Authenticating Agent hereunder, if such successor corporation is
otherwise eligible under this Section 614, without the execution
or filing of any paper or any further act on the part of the
parties hereto or the Authenticating Agent or such successor
corporation.

          An Authenticating Agent may resign at any time by
giving written notice of resignation to the Trustee and to the
Company.  The Trustee may at any time terminate the agency of any
Authenticating Agent by giving written notice of termination to
such Authenticating Agent and to the Company.  Upon receiving
such a notice of resignation or upon such a termination, or in
case at any time any Authenticating Agent shall cease to be
eligible under this Section 614, the Trustee may appoint a
successor Authenticating Agent which shall be acceptable to the
Company and shall mail notice of such appointment to all Holders
of Securities of the series with respect to which such
Authenticating Agent will serve, as the names and addresses of
such Holders appear on the Security Register.  Any successor
Authenticating Agent, upon acceptance of its appointment
hereunder, shall become vested with all the rights, powers and
duties of its predecessor hereunder, with like effect as if
originally named as an Authenticating Agent.  No successor
Authenticating Agent shall be appointed unless eligible under the
provisions of this Section 614.

          The Trustee agrees to pay to each Authenticating Agent
from time to time reasonable compensation for its services under
this Section 614, and the Trustee shall be entitled to be
reimbursed for such payments pursuant to Section 607 hereof.

          If an appointment with respect to one or more series of
Securities is made pursuant to this Section 614, the Securities
of such series may have endorsed thereon, in addition to the
Trustee's certificate of authentication, an alternate certificate
of authentication in the following form:

          This is one of the Securities of the series designated
herein referred to in the within-mentioned Indenture.


                              [NAME OF TRUSTEE],

                         ARTICLE SEVEN

       HOLDERS' LISTS AND REPORTS BY TRUSTEE AND COMPANY

SECTION 701.  Company to Furnish Trustee Names and Addresses of
              Holders.

          The Company will furnish or cause to be furnished to
the Trustee with respect to the Securities of each series

          (a)  semi-annually, not later than 15 days after each
     Regular Record Date, or, in the case of any series of
     Securities on which semi-annual interest is not payable, not
     more than 15 days after such semi-annual dates as may be
     specified by the Trustee, a list, in such form as the
     Trustee may reasonably require, of the names and addresses
     of the Holders as of such Regular Record Date or semi-annual
     date, as the case may be, and

          (b)  at such other times as the Trustee may request in
     writing, within 30 days after the receipt by the Company of
     any such request, a list of similar form and content as of a
     date not more than 15 days prior to the time such list is
     furnished;

provided, however, that if and so long as the Trustee is Security
Registrar for any series of Securities, no such list shall be
required to be furnished with respect to any such series.

SECTION 702.  Preservation of Information; Communications to
              Holders.

          (a)  The Trustee shall preserve, in as current a form
as is reasonably practicable, the names and addresses of Holders
contained in the most recent list furnished to the Trustee as
provided in Section 701 hereof and the names and addresses of
Holders received by the Trustee in its capacity as Security
Registrar.  The Trustee may destroy any list furnished to it as
provided in Section 701 hereof upon receipt of a new list so
furnished.

          (b)  If three or more Holders (herein referred to as
"applicants") apply in writing to the Trustee, and furnish to the
Trustee reasonable proof that each such applicant has owned a
Security for a period of at least six months preceding the date
of such application, and such application states that the
applicants desire to communicate with other Holders with respect
to their rights under this Indenture or under the Securities and
is accompanied by a copy of the form of proxy or other
communication which such applicants propose to transmit, then the
Trustee shall, within five business days after the receipt of
such application, at its election, either

          (i)  afford such applicants access to the information
     preserved at the time by the Trustee in accordance with
     Section 702(a) hereof, or

         (ii)  inform such applicants as to the approximate
     number of Holders whose names and addresses appear in the
     information preserved at the time by the Trustee in
     accordance with Section 702(a) hereof, and as to the
     approximate cost of mailing to such Holders the form of
     proxy or other communication, if any, specified in such
     application.

          If the Trustee shall elect not to afford such
applicants access to such information, the Trustee shall, upon
the written request of such applicants, mail to each Holder whose
name and address appear in the information preserved at the time
by the Trustee in accordance with Section 702(a) hereof a copy of
the form of proxy or other communication which is specified in
such request, with reasonable promptness after a tender to the
Trustee of the material to be mailed and of payment, or provision
for the payment, of the reasonable expenses of mailing, unless
within five days after such tender the Trustee shall mail to such
applicants and file with the Commission, together with a copy of
the material to be mailed, a written statement to the effect
that, in the opinion of the Trustee, such mailing would be
contrary to the best interest of the Holders or would be in
violation of applicable law.  Such written statement shall
specify the basis of such opinion.  If the Commission, after
opportunity for a hearing upon the objections specified in the
written statement so filed, shall enter an order refusing to
sustain any of such objections or if, after the entry of an order
sustaining one or more of such objections, the Commission shall
find, after notice and opportunity for hearing, that all the
objections so sustained have been met and shall enter an order so
declaring, the Trustee shall mail copies of such material to all
such Holders with reasonable promptness after the entry of such
order and the renewal of such tender; otherwise the Trustee shall
be relieved of any obligation or duty to such applicants
respecting their application.

          (c)  Every Holder of Securities, by receiving and
holding the same, agrees with the Company and the Trustee that
neither the Company nor the Trustee nor any agent of either of
them shall be held accountable by reason of the disclosure of any
such information as to the names and addresses of the Holders in
accordance with Section 702(b) hereof, regardless of the source
from which such information was derived, and that the Trustee
shall not be held accountable by reason of mailing any material
pursuant to a request made under Section 702(b) hereof.

SECTION 703.  Reports by Trustee.

          (a)  Within 60 days after the first May 15 which occurs
not less than 60 days following the first date of issuance of
Securities of any series under this Indenture and within 60 days
after May 15 in every year thereafter, the Trustee shall transmit
by mail to all Holders, as their names and addresses appear in
the Security Register, a brief report dated as of such May 15
with respect to any of the following events which may have
occurred within the previous 12 months (but if no such event has
occurred within such period no report need be transmitted):

     hereof and its qualifications under Section 608 hereof;

          (2)  the creation of or any material change to a
     relationship specified in Section 608 hereof;

          (3)  the character and amount of any advances (and if

     for the reimbursement of which it claims or may claim a lien
     or charge, prior to that of the Securities, on any property
     or funds held or collected by it as Trustee, except that the
     Trustee shall not be required (but may elect) to report such
     advances if such advances so remaining unpaid aggregate not
     more than 1/2 of 1% of the principal amount of the
     Securities Outstanding on the date of such report;

          (4)  any change to the amount, interest rate and
     maturity date of all other indebtedness owing by the Company
     (or by any other obligor on the Securities) to the Trustee

     a brief description of any property held as collateral
     security therefor, except an indebtedness based upon a
     creditor relationship arising in any manner described in
     Sections 613(b)(2), (3), (4) or (6) hereof;

          (5)  any change to the property and funds, if any,
     physically in the possession of the Trustee as such on the
     date of such report;

          (6)  any release, or release and substitution, of
     property subject to the lien of this Indenture (and the
     consideration therefor, if any) which it has not previously
     reported;

          (7)  any additional issue of Securities which the
     Trustee has not previously reported; and

          (8)  any action taken by the Trustee in the performance
     of its duties hereunder which it has not previously reported
     and which in its opinion materially affects the Securities,
     except action in respect of a default, notice of which has
     been or is to be withheld by the Trustee in accordance with
     Section 602 hereof.

          (b)  The Trustee shall transmit by mail to all Holders,
as their names and addresses appear in the Security Register, a
brief report with respect to (1) the release, or release and
substitution, of property subject to the lien of this Indenture
(and the consideration therefor, if any) unless the fair value of
such property, as set forth in the certificate required by
Section 1306 hereof, is less than 10% of the principal amount of
Securities outstanding at the time of such release, or release
and substitution, and (2) the character and amount of any
advances (and if the Trustee elects so to state, the
circumstances surrounding the making thereof) made by the Trustee
(as such) since the date of the last report transmitted pursuant
to Subsection (a) of this Section 703 (or if no such report has
yet been so transmitted, since the date of execution of this
instrument) for the reimbursement of which it claims or may claim
a lien or charge, prior to that of the Securities, on property or
funds held or collected by it as Trustee and which it has not

Trustee shall not be required (but may elect) to report such
advances if such advances remaining unpaid at any time aggregate

such time.

          (c)  A copy of each such report shall, at the time of

     or Section 513 hereof, except to increase any such
     percentage or to provide that certain other provisions of
     this Indenture cannot be modified or waived without the
     consent of the Holder of each Outstanding Security affected
     thereby, provided, however, that this clause shall not be
     deemed to require the consent of any Holder with respect to
     changes in the references to "the Trustee" and concomitant
     changes in this Section 902, or the deletion of this
     proviso, in accordance with the requirements of Sections
     611(b) and 901(8) hereof.

A supplemental indenture which changes or eliminates any covenant
or other provision of this Indenture which has expressly been
included solely for the benefit of one or more particular series
of Securities, or which modifies the rights of the Holders of
Securities of such series with respect to such covenant or other
provision, shall be deemed not to affect the rights under this
Indenture of the Holders of Securities of any other series.

          It shall not be necessary for any Act of Holders under
this Section 902 to approve the particular form of any proposed
supplemental indenture, but it shall be sufficient if such Act
shall approve the substance thereof.

SECTION 903.  Execution of Supplemental Indentures.

          In executing, or accepting the additional trusts
created by, any supplemental indenture permitted by this Article
or the modifications thereby of the trusts created by this
Indenture, the Trustee shall be entitled to receive, and (subject
to Section 601 hereof) shall be fully protected in relying upon,
an Opinion of Counsel stating that the execution of such
supplemental indenture is authorized or permitted by this
Indenture.  The Trustee may, but shall not be obligated to, enter
into any such supplemental indenture which affects the Trustee's
own rights, duties or immunities under this Indenture or
otherwise.

SECTION 904.  Effect of Supplemental Indentures.

          Upon the execution of any supplemental indenture under
this Article, this Indenture shall be modified in accordance
therewith, and such supplemental indenture shall form a part of
this Indenture for all purposes; and every Holder of Securities
theretofore or thereafter authenticated and delivered hereunder
shall be bound thereby.

SECTION 905.  Conformity with Trust Indenture Act.

          Every supplemental indenture executed pursuant to this
Article shall conform to the requirements of the Trust Indenture
Act as then in effect.

SECTION 906.  Reference in Securities to Supplemental Indentures.

          Securities of any series authenticated and delivered
after the execution of any supplemental indenture pursuant to
this Article may, and shall if required by the Trustee, bear a
notation in form approved by the Trustee as to any matter
provided for in such supplemental indenture.  If the Company
shall so determine, new Securities of any series so modified as
to conform, in the opinion of the Trustee and the Company, to any
such supplemental indenture may be prepared and executed by the
Company and authenticated and delivered by the Trustee in
exchange for Outstanding Securities of such series.


                          ARTICLE TEN

                           COVENANTS

SECTION 1001.  Payment of Principal, Premium and Interest.

          The Company covenants and agrees for the benefit of
each series of Securities that it will duly and punctually pay
the principal of (and premium, if any) and interest, if any, on
the Securities of that series in accordance with the terms of the
Securities and this Indenture.

SECTION 1002.  Maintenance of Office or Agency.

          The Company will maintain in each Place of Payment for
any series of Securities an office or agency where Securities of
that series may be presented or surrendered for payment, where
Securities of that series may be surrendered for registration of
transfer or exchange and where notices and demands to or upon the
Company in respect of the Securities of that series and this
Indenture may be served.  The Company will give prompt written
notice to the Trustee of the location, and any change in the
location, of such office or agency.  If at any time the Company
shall fail to maintain any such required office or agency or
shall fail to furnish the Trustee with the address thereof, such
presentations, surrenders, notices and demands may be made or
served at the Corporate Trust Office of the Trustee, and, in such
event, the Trustee shall act as the Company's agent to receive
all such presentations, surrenders, notices and demands.

          The Company may also from time to time designate one or
more other offices or agencies where the Securities of one or
more series may be presented or surrendered for any or all such
purposes and may from time to time rescind such designations;
provided, however, that no such designation or rescission shall
in any manner relieve the Company of its obligation to maintain
an office or agency in each Place of Payment for Securities of
any series for such purposes.  The Company will give prompt
written notice to the Trustee of any such designation or
rescission and of any change in the location of any such other
office or agency.

SECTION 1003.  Money for Securities Payments to Be Held in Trust.

          If the Company shall at any time act as its own Paying
Agent with respect to any series of Securities, it will, on or
before each due date of the principal of (and premium, if any) or
interest, if any, on any of the Securities of that series,
segregate and hold in trust for the benefit of the Persons
entitled thereto a sum sufficient to pay the principal (and
premium, if any) or interest, if any, so becoming due until such
sums shall be paid to such Persons or otherwise disposed of as
herein provided and will promptly notify the Trustee of its
action or failure so to act.

          Whenever the Company shall have one or more Paying
Agents for any series of Securities, it will, no later than 11:00
a.m., New York Time, on or prior to each due date of the
principal of (and premium, if any) or interest, if any, on any
Securities of that series, deposit with a Paying Agent a sum in
immediately available funds sufficient to pay the principal (and
premium, if any) or interest so becoming due, such sum to be held
in trust for the benefit of the Persons entitled to such
principal, premium or interest, and (unless such Paying Agent is
the Trustee) the Company will promptly notify the Trustee of its
failure so to act.

          The Company will cause each Paying Agent for any series
of Securities other than the Trustee to execute and deliver to
the Trustee an instrument in which such Paying Agent shall agree
with the Trustee, subject to the provisions of this Section 1003,
that such Paying Agent will:

          (1)  hold all sums held by it for the payment of the
     principal of (and premium, if any) or interest, if any, on
     Securities of that series in trust for the benefit of the
     Persons entitled thereto until such sums shall be paid to
     such Persons or otherwise disposed of as herein provided;

          (2)  give the Trustee notice of any default by the
     Company (or any other obligor upon the Securities of that
     series) in the making of any payment of principal (and
     premium, if any) or interest, if any, on the Securities of
     that series; and

          (3)  at any time during the continuance of any such
     default, upon the written request of the Trustee, forthwith
     pay to the Trustee all sums so held in trust by such Paying
     Agent.

          The Company may at any time, for the purpose of
obtaining the satisfaction and discharge of this Indenture or for
any other purpose, pay, or by Company Order direct any Paying
Agent to pay, to the Trustee all sums held in trust by the
Company or such Paying Agent, such sums to be held by the Trustee
upon the same trusts as those upon which such sums were held by
the Company or such Paying Agent; and, upon such payment by any
Paying Agent to the Trustee, such Paying Agent shall be released
from all further liability with respect to such money.

          Any money deposited with the Trustee or any Paying
Agent, or then held by the Company, in trust for the payment of
the principal of (and premium, if any) or interest, if any, on
any Security of any series and remaining unclaimed for two years
after such principal (and premium, if any) or interest has become
due and payable shall be paid to the Company on Company Request,
or (if then held by the Company) shall be discharged from such
trust; and the Holder of such Security shall thereafter, as an
unsecured general creditor, look only to the Company for payment
thereof, and all liability of the Trustee or such Paying Agent
with respect to such trust money, and all liability of the
Company as trustee thereof, shall thereupon cease; provided,
however, that the Trustee or such Paying Agent, before being
required to make any such repayment, shall at the written request
and expense of the Company cause to be published once, in a
newspaper published in the English language, customarily
published on each Business Day and of general circulation in [
] notice that such money remains unclaimed and that, after a date
specified therein, which shall not be less than 30 days from the
date of such publication, any unclaimed balance of such money
then remaining will be repaid to the Company.

SECTION 1004.  Corporate Existence.

          Subject to Article Eight, the Company will do or cause
to be done all things necessary to preserve and keep in full
force and effect its corporate existence and will use its best
efforts to do or cause to be done all things necessary to
preserve and keep in full force and effect its rights (charter
and statutory) and franchises; provided, however, that the
Company shall not be required to preserve any such right or
franchise if the Board of Directors shall determine that the
preservation thereof is no longer desirable in the conduct of the
business of the Company.

SECTION 1005.  Maintenance of Properties.

          The Company will cause all properties used or useful in
the conduct of its business or the business of any Subsidiary to
be maintained and kept in good condition, repair and working
order and supplied with all necessary equipment and will cause to
be made all necessary repairs, renewals, replacements,
betterments and improvements thereof, all as in the judgment of
the Company may be necessary so that the business carried on in
connection therewith may be properly and advantageously conducted
at all times; provided, however, that nothing in this Section
1005 shall prevent the Company from discontinuing the operation
or maintenance of any of such properties if such discontinuance
is, in the judgment of the Company, desirable in the conduct of
its business or the business of any Subsidiary.

SECTION 1006.  Maintenance of Insurance.

          The Company will maintain, and will cause each of its
Subsidiaries to maintain, with insurers the Company reasonably
believes to be financially sound and reputable, insurance deemed
adequate by the Company with respect to its properties and
business and the properties and business of its Subsidiaries
against loss or damage of the kinds customarily insured against
by corporations in the same or similar business.  Such insurance
may be subject to co-insurance, deductibility or similar clauses
which, in effect, result in self-insurance of certain losses,
provided that such self-insurance is in accord with the practices
of corporations in the same or similar business and adequate
insurance reserves are maintained in connection with such self-
insurance.

SECTION 1007.  Limitation on Liens.

          Nothing in this Indenture or in the Securities shall in
any way restrict or prevent the Company or any Subsidiary from
incurring any indebtedness; provided that if this covenant shall
be made applicable to the Securities of a particular series, the
Company covenants and agrees that it will not, nor will it permit
any Subsidiary to, issue, assume or guarantee any notes, bonds,
debentures or other similar evidences of indebtedness for money
borrowed ("Debt") secured by a Mortgage upon any property or
assets without effectively providing that the Outstanding
Securities to which this section shall have been made applicable
(together with, if the Company so determines, any other
indebtedness or obligation then existing or thereafter created
ranking equally with the Securities) shall be secured equally and
ratably with (or prior to) such Debt so long as such Debt shall
be so secured (provided, that for the purpose of providing such
equal and ratable security, the principal amount of Outstanding
Securities of any series of Original Issue Discount Securities
shall be such portion of the principal amount as may be specified
in the terms of that series), except that the foregoing
provisions shall not apply to:

          (a)  Mortgages in existence on the date of original
     issue of the Securities of any series to which this
     restriction is made applicable (including without limitation
     any obligations issued or incurred, or to be issued or
     incurred, under the First Mortgage Indenture);

          (b)  Mortgages created solely for the purpose of
     securing Debt incurred to finance, refinance or refund the
     purchase price or cost (including the cost of construction)
     of property or assets acquired after the date hereof (by
     purchase, construction or otherwise), or Mortgages in favor
     of guarantors of obligations or Debt representing, or
     incurred to finance, refinance or refund, such purchase
     price or cost, provided that no such Mortgage shall extend
     to or cover any property or assets other than the property
     or assets so acquired and improvements thereon (other than,
     in the case of Mortgages securing Debt incurred to finance
     construction or improvement costs, any theretofore
     unimproved real property on which the property so
     constructed, or the improvement, is located);

          (c)  Mortgages which secure only indebtedness owing by
     a Subsidiary to the Company, to one or more Subsidiaries or
     to the Company and one or more Subsidiaries;

          (d)  Mortgages on any property or assets acquired from
     a corporation which is merged with or into the Company or
     any Subsidiary, or any Mortgages on the property or assets
     of any Corporation or other entity existing at the time such
     Corporation or other entity becomes a Subsidiary and, in
     either such case, is not created as a result of or in
     connection with or in anticipation of any such transaction
     (unless such Mortgage was created to secure or provide for
     the payment of any part of the purchase price of such
     corporation);

          (e)  Any Mortgage on any property or assets existing at
     the time of acquisition thereof and which is not created as
     a result of or in connection with or in anticipation of such
     acquisition (unless such Mortgage was created to secure or
     provide for the payment of any part of the purchase price of
     such property or assets); or

          (f)  Any extension, renewal or replacement (or
     successive extensions, renewals or replacements), in whole
     or in part, of any Mortgage referred to in the foregoing
     clauses (a) through (e) or of any Debt secured thereby,
     provided that the principal amount of Debt so secured
     thereby shall not exceed the principal amount of Debt so
     secured at the time of such extension, renewal or
     replacement, and that such extension, renewal or replacement
     Mortgage shall be limited to all or part of substantially
     the same property which secured the Mortgage extended,
     renewed or replaced (plus improvements on or additions to
     such property).

          Notwithstanding the foregoing provisions of this
Section 1007, the Company and one or more Subsidiaries may issue,
assume or guarantee Debt secured by Mortgages which would
otherwise be subject to the foregoing restrictions in an
aggregate principal amount which, together with the aggregate
outstanding principal amount of all other Debt of the Company and
its Subsidiaries which would otherwise be subject to the
foregoing restrictions (not including Debt permitted to be
secured under clauses (a) through (f)) hereof does not at the
time of issuance, assumption, or guarantee thereof exceed 10% of
Net Tangible Assets.

          The following types of transactions, among others,
shall not be deemed to create Debt secured by Mortgages:

          Mortgages required by any contract or statute in order
     to permit the Company or a Subsidiary to perform any
     contract or subcontract made by it with or at the request of
     a governmental entity or any department, agency or
     instrumentality thereof, or to secure partial, progress,
     advance or any other payments to the Company or any
     Subsidiary by a governmental entity or any department,
     agency or instrumentality thereof pursuant to the provisions
     of any contract or statute.

SECTION 1008.  Statement by Officers as to Default.

          The Company will deliver to the Trustee on or before
May 15 in each year, an Officers' Certificate stating that in the
course of the performance by each signer of his duties as an
officer of the Company he would normally have knowledge of any
default by the Company in the performance and observance of any
of the covenants contained in Sections 1001 to 1007 hereof,
stating whether or not he has knowledge of any such default and,
if so, specifying each such default of which such signer has
knowledge and the nature thereof.  Upon the occurrence of a
"default" as defined in the First Mortgage Indenture prior to the
Release Date, the Company shall promptly notify the Trustee of
such event.

SECTION 1009.  Opinions of Counsel.

          The Company shall deliver to the Trustee:

          (a) promptly after the execution and delivery of this
     Indenture and of any indenture supplemental to this
     Indenture but prior to the Release Date, an Opinion of
     Counsel either stating that, in the opinion of such counsel,
     this Indenture or such supplemental indenture and any
     financing or continuation statements have been properly
     recorded and filed so as to make effective and to perfect
     the security interest of the Trustee intended to be created
     by this Indenture for the benefit of the Holders from time
     to time of the Securities in the Senior Note Mortgage Bonds,
     and reciting the details of such action, or stating that, in
     the opinion of such counsel, no such action is necessary to
     perfect or make such security interest effective and stating
     what, if any, action of the foregoing character may
     reasonably be expected to become necessary prior to the next
     succeeding March 1 to maintain, perfect and make such
     security interest effective; and

          (b) on or before March 1 of each year, beginning in
     1997, and prior to the Release Date, an Opinion of Counsel
     either stating that in the opinion of such counsel such
     action has been taken, since the date of the most recent
     Opinion of Counsel furnished pursuant to this Section
     1009(b) or the first Opinion of Counsel furnished pursuant
     to Section 1009(a) hereof, with respect to the recording,
     filing, rerecording, or refiling of this Indenture, each
     supplemental indenture and any financing or continuation
     statements, as is necessary to maintain and perfect the
     security interest of the Trustee intended to be created by
     this Indenture for the benefit of the Holders from time to
     time of the Securities in the Senior Note Mortgage Bonds,
     and reciting the details of such action, or stating that in
     the opinion of such counsel no such action is necessary to
     maintain and perfect such security interest and stating
     what, if any, action of the foregoing character may
     reasonably be expected to become necessary prior to the next
     succeeding March 1 to maintain, perfect and make such
     security interest effective.

or condition set forth in Sections 801 and 1004 to 1007 hereof
with respect to the Securities of any series, provided that the
following conditions shall have been satisfied:

     this Section 1010) as trust funds in trust, specifically
     pledged as security for, and dedicated solely to, the
     benefit of the Holders of the Securities of such series, (i)
     money in the currency or units of currency in which such
     Securities are payable in an amount, or (ii) (except as
     provided in a supplemental indenture with respect to such
     series) if Securities of such series are not subject to
     repurchase at the option of Holders, (A) U.S. Government
     Obligations (denominated in the same currency or units of
     currency in which such Securities are payable) which through
     the payment of interest and principal in respect thereof in
     accordance with their terms will provide not later than one
     day before the due date of any payment referred to in clause
     (x) or (y) of this subparagraph (1) money in an amount, or
     (B) a combination thereof, in each case sufficient, in the
     opinion of a nationally recognized firm of independent
     certified public accountants expressed in a written
     certification thereof delivered to the Trustee, to pay and
     discharge, and which the Trustee shall be instructed to

     such series then listed on any national securities exchange
     to be delisted as a result thereof; and (iii) that the

     company under the Investment Company Act of 1940;

comply with any term, provision or condition set forth in
Sections 801 and 1004 to 1007 hereof, inclusive, with respect to
the Securities of any series if before the time for such
compliance the Holders of at least a majority in aggregate
principal amount of the Outstanding Securities of such series
shall, by Act of such Holders, either waive such compliance in
such instance or generally waive compliance with such term,
provision or condition, but no such waiver shall extend to or

                         ARTICLE ELEVEN

                    REDEMPTION OF SECURITIES

SECTION 1101.  Applicability of Article.

          Securities of any series which are redeemable before
their Stated Maturity shall be redeemable in accordance with
their terms and (except as otherwise specified as contemplated by
Section 301 hereof for Securities of any series) in accordance
with this Article Eleven.

SECTION 1102.  Election to Redeem; Notice to Trustee.

          The election of the Company to redeem any Securities
shall be authorized by a Board of Directors resolution and
evidenced by an Officers' Certificate.  In case of any redemption
at the election of the Company of less than all the Securities of
any series, the Company shall, at least 60 days prior to the
Redemption Date fixed by the Company (unless a shorter notice
shall be satisfactory to the Trustee), notify the Trustee of such
Redemption Date and of the principal amount of Securities of such
series to be redeemed.  In the case of any redemption of
Securities prior to the expiration of any restriction on such
redemption provided in the terms of such Securities or elsewhere
in this Indenture, or pursuant to an election by the Company
which is subject to a condition specified in the terms of such
Securities or elsewhere in this Indenture, the Company shall
furnish the Trustee with an Officers' Certificate evidencing
compliance with such restriction or condition.

SECTION 1103.  Selection by Trustee of Securities to
               Be Redeemed.

          If less than all the Securities of any series are to be
redeemed, the particular Securities to be redeemed shall be
selected not more than 60 days prior to the Redemption Date by
the Trustee, from the Outstanding Securities of such series not
previously called for redemption, by such method as the Trustee
shall deem fair and appropriate and which may provide for the
selection for redemption of portions (equal to the minimum
authorized denomination for Securities of that series or any
integral multiple thereof) of the principal amount of Securities
of such series of a denomination larger than the minimum
authorized denomination for Securities of that series.

          Securities shall be excluded from eligibility for
selection for redemption if they are identified by registration
and certificate number in a written statement signed by an
authorized officer of the Company and delivered to the Security
Registrar at least 60 days prior to the Redemption Date as being
owned of record and beneficially by, and not pledged or
hypothecated by either (a) the Company or (b) an entity
specifically identified in such written statement which is an
Affiliate of the Company.

          The Trustee shall promptly notify the Company in
writing of the Securities selected for redemption and, in the
case of any Securities selected for partial redemption, the
principal amount thereof to be redeemed.

          For all purposes of this Indenture, unless the context
otherwise requires, all provisions relating to the redemption of
Securities shall relate, in the case of any Securities redeemed
or to be redeemed only in part, to the portion of the principal
amount of such Securities which has been or is to be redeemed.

SECTION 1104.  Notice of Redemption.

          Notice of redemption shall be given by first-class
mail, postage prepaid, mailed not less than 30 nor more than 60
days prior to the Redemption Date, to each Holder of Securities
to be redeemed, at his address appearing in the Security
Register.

          All notices of redemption shall state:

          (1)  the Redemption Date,

          (2)  the Redemption Price,

          (3)  if less than all the Outstanding Securities of any
     series are to be redeemed, the identification (and, in the
     case of partial redemption, the principal amounts) of the
     particular Securities to be redeemed,

          (4)  that on the Redemption Date the Redemption Price
     will become due and payable upon each such Security to be
     redeemed and, if applicable, that interest thereon will
     cease to accrue on and after said date,

          (5)  the place or places where such Securities are to
     be surrendered for payment of the Redemption Price, and

          (6)  that the redemption is for a sinking fund, if such
     is the case.

          Notice of redemption of Securities to be redeemed at
the election of the Company shall be given by the Company or, at
the Company's request, by the Trustee in the name and at the
expense of the Company.

SECTION 1105.  Deposit of Redemption Price.

          On or prior to any Redemption Date, the Company shall
deposit with the Trustee or with a Paying Agent (or, if the
Company is acting as its own Paying Agent, segregate and hold in
trust as provided in Section 1003 hereof) an amount of money
sufficient to pay the Redemption Price of, and (except if the
Redemption Date shall be an Interest Payment Date) accrued
interest on, all the Securities which are to be redeemed on that
date (to the extent that such amounts are not already on deposit
at such time in accordance with the provisions of Sections 401,
403 or 1010 hereof).

SECTION 1106.  Securities Payable on Redemption Date.

          Notice of redemption having been given as aforesaid,
the Securities so to be redeemed shall, on the Redemption Date,
become due and payable at the Redemption Price therein specified,
and from and after such date (unless the Company shall default in
the payment of the Redemption Price and accrued and unpaid
interest) such Securities shall cease to bear interest.  Upon
surrender of any such Security for redemption in accordance with
said notice, such Security shall be paid by the Company at the
Redemption Price, together with accrued and unpaid interest to
the Redemption Date; provided, however, that installments of
interest whose Stated Maturity is on or prior to the Redemption
Date shall be payable to the Holders of such Securities, or one
or more Predecessor Securities, registered as such at the close
of business on the relevant Record Dates according to their terms
and the provisions of Section 307 hereof.

          If any Security called for redemption shall not be so
paid upon surrender thereof for redemption, the principal (and
premium, if any) shall, until paid, bear interest from the
Redemption Date at the rate prescribed therefor in the Security.

SECTION 1107.  Securities Redeemed in Part.

          Any Security (including any Global Security) which is
to be redeemed only in part shall be surrendered at a Place of
Payment therefor (with, if the Company or the Trustee so
requires, due endorsement by, or a written instrument of transfer
in form satisfactory to the Company and the Trustee duly executed
by, the Holder thereof or his attorney duly authorized in
writing), and the Company shall execute, and the Trustee shall
authenticate and deliver to the Holder of such Security without
service charge, a new Security or Securities of the same series,
of any authorized denomination as requested by such Holder, in
aggregate principal amount equal to and in exchange for the
unredeemed portion of the principal of the Security so
surrendered; provided, that if a Global Security is so
surrendered, the new Global Security shall be in a denomination
equal to the unredeemed portion of the principal of the Global
Security so surrendered.

                         ARTICLE TWELVE

                         SINKING FUNDS

SECTION 1201.  Applicability of Article.

          The provisions of this Article shall be applicable to
any sinking fund for the retirement of Securities of a series
except as otherwise specified as contemplated by Section 301
hereof for Securities of such series.

          The minimum amount of any sinking fund payment provided
for by the terms of Securities of any series is herein referred
to as a "mandatory sinking fund payment", and any payment in
excess of such minimum amount provided for by the terms of
Securities of any series is herein referred to as an "optional
sinking fund payment".  If provided for by the terms of
Securities of any series, the cash amount of any sinking fund
payment may be subject to reduction as provided in Section 1202
hereof.  Each sinking fund payment shall be applied to the
redemption of Securities of any series as provided for by the
terms of Securities of such series.

SECTION 1202.  Satisfaction of Sinking Fund Payments with
               Securities.

          In lieu of making all or any part of any mandatory
sinking fund payment with respect to any series of Securities in
cash, the Company may at its option (a) deliver to the Trustee
Securities of such series theretofore purchased or otherwise
acquired (except upon redemption pursuant to the mandatory
sinking fund) by the Company or receive credit for Securities of
such series (not previously so credited) theretofore purchased or
otherwise acquired (except as aforesaid) by the Company and
delivered to the Trustee for cancellation pursuant to Section 309
hereof, (b) receive credit for optional sinking fund payments
(not previously so credited) made pursuant to this Section 1202,
or (c) receive credit for Securities of such series (not
previously so credited) redeemed by the Company through any
optional redemption provision contained in the terms of such
series.  Securities so delivered or credited shall be received or
credited by the Trustee at the sinking fund Redemption Price
specified in such Securities.

SECTION 1203.  Redemption of Securities for Sinking Fund.

          Not less than 60 days prior to each sinking fund
payment date for any series of Securities, the Company will
deliver to the Trustee an Officers' Certificate specifying (a)
the amount of the next ensuing sinking fund payment for that
series pursuant to the terms of that series, (b) whether or not
the Company intends to exercise its right, if any, to make an
optional sinking fund payment with respect to such series on the
next ensuing sinking fund payment date and, if so, the amount of
such optional sinking fund payment, and (c) the portion thereof,
if any, which is to be satisfied by payment of cash and the
portion thereof, if any, which is to be satisfied by delivering
and crediting Securities of that series pursuant to Section 1202
hereof, and will also deliver to the Trustee any Securities to be
so delivered.  Such written statement shall be irrevocable and
upon its receipt by the Trustee the Company shall become
unconditionally obligated to make all the cash payments or
payments therein referred to, if any, on or before the next
succeeding sinking fund payment date.  Failure of the Company, on
or before any such 60th day, to deliver such written statement
and Securities specified in this paragraph, if any, shall not
constitute a default but shall constitute, on and as of such
date, the irrevocable election of the Company (i) that the
mandatory sinking fund payment for such series due on the next
succeeding sinking fund payment date shall be paid entirely in
cash without the option to deliver or credit Securities of such
series in respect therefor and (ii) that the Company will make no
optional sinking fund payment with respect to such series as
provided in this Section 1203.

            Not less than 30 days before each such sinking fund
payment date the Trustee shall select the Securities to be
redeemed upon such sinking fund payment date in the manner
specified in Section 1103 hereof and cause notice of the
redemption thereof to be given in the name of and at the expense
of the Company in the manner provided in Section 1104 hereof.
Such notice having been duly given, the redemption of such
Securities shall be made upon the terms and in the manner stated
in Sections 1105, 1106 and 1107 hereof.

          The Trustee shall not redeem or cause to be redeemed
any Security of a series with sinking fund moneys or mail any
notice of redemption of Securities of such series by operation of
the sinking fund during the continuance of a default in payment
of interest with respect to Securities of that series or an Event
of Default with respect to the Securities of that series except
that, where the mailing of notice of redemption of any Securities
shall theretofore have been made, the Trustee shall redeem or
cause to be redeemed such Securities, provided that it shall have
received from the Company a sum sufficient for such redemption.
Except as aforesaid, any moneys in the sinking fund for such
series at the time when any such default or Event of Default,
shall occur, and any moneys thereafter paid into the sinking
fund, shall, during the continuance of such default or Event of
Default, be deemed to have been collected under Article Five and
held for the payment of all such Securities.  In case such Event
of Default shall have been waived as provided in Section 513
hereof or the default or Event of Default cured on or before the
60th day preceding the sinking fund payment date, such moneys
shall thereafter be applied on the next succeeding sinking fund
payment date in accordance with this Section 1203 to the
redemption of such Securities.


                        ARTICLE THIRTEEN

                   SENIOR NOTE MORTGAGE BONDS

    SECTION 1301.  Delivery of Senior Note Mortgage Bonds to the Trustee.

          Subject to the provisions of Section 401 and Section
1310 hereof, the Company (a) shall, from time to time prior to
the Release Date, deliver to the Trustee, upon the issuance of a
series of Securities hereunder, Senior Note Mortgage Bonds
conforming to the requirements of Section 1309 hereof, fully
registered in the name of the Trustee, in trust for the benefit
of the Holders from time to time of the Securities issued under
this Indenture as security for any and all obligations of the
Company under the Securities, including, but not limited to,
(1) the full and prompt payment of the principal of the
Securities when and as the same shall become due and payable in
accordance with the terms and provisions of this Indenture or the
Securities, either at the stated maturity thereof, upon
acceleration of the maturity thereof or upon redemption, and
(2) the full and prompt payment of any interest on the Securities
when and as the same shall become due and payable in accordance
with the terms and provisions of this Indenture or the Securities
and (b) shall deliver concurrently therewith to the Trustee the
certificate of the Expert required by Section 1306 hereof.

          SECTION 1302.  Receipt.

          The Trustee shall accept and acknowledge receipt of the
Senior Note Mortgage Bonds and Expert certificate described in
Section 1301 hereof upon the delivery thereof in accordance with
said Section 1301.

          SECTION 1303.  Senior Note Mortgage Bonds Held by the Trustee.

          The Trustee, as a Holder of Senior Note Mortgage Bonds,
shall attend any meeting of bondholders under the First Mortgage
Indenture as to which it receives due notice, or, at its option,
shall deliver its proxy in connection therewith.  Either at such
meeting, or otherwise where consent of holders of first mortgage
bonds issued under the First Mortgage Indenture is sought without
a meeting, the Trustee shall vote all of the Senior Note Mortgage
Bonds held by it, or shall consent or withhold its consent with
respect thereto, as directed by the Holders of not less than a
majority in the aggregate principal amount of the outstanding
Securities; provided, however, the Trustee shall not vote as such
holder of any particular series of Senior Note Mortgage Bonds in
favor of, or give its consent to, any action which, in the
Trustee's opinion, would materially adversely affect such series
of Senior Note Mortgage Bonds in a manner not shared generally by
all other Senior Note Mortgage Bonds, except upon notification by
the Trustee to the Holders of the related series of Securities of
such proposal and consent thereto of the Holders of not less than
a majority in aggregate principal amount of the outstanding
Securities of such series.

        SECTION 1304.  No Transfer of Senior Note Mortgage Bonds; Exception.

          Except as required to effect an assignment to a
successor trustee under this Indenture or pursuant to Section
1305 or Section 1308 hereof, the Trustee shall not sell, assign
or transfer the Senior Note Mortgage Bonds and the Company shall
issue stop transfer instructions to the First Mortgage Trustee
and any transfer agent under the First Mortgage Indenture to
effect compliance with this Section 1304.

        SECTION 1305.  Delivery to the Company of All Senior Note Mortgage
                       Bonds.

          When the obligation of the Company to make payment with
respect to the principal of and premium, if any, and interest on
the Senior Note Mortgage Bonds shall be satisfied or deemed
satisfied pursuant to Section 401 or Section 1310 hereof, the
Trustee shall, upon written request of the Company and receipt of
the certificate of the Expert described in Section 1306(b) hereof
(if such certificate is then required by Section 1306(b) hereof),
deliver to the Company without charge therefor all of the Senior
Note Mortgage Bonds, together with such appropriate instruments
of transfer or release as may be reasonably requested by the
Company. All Senior Note Mortgage Bonds delivered to the Company
in accordance with this Section 1305 shall be delivered by the
Company to the First Mortgage Trustee for cancellation.

          SECTION 1306.  Fair Value Certificate.

          (a) Upon the delivery by the Company to the Trustee of
Senior Note Mortgage Bonds pursuant to Section 1301 hereof and
subject to Section 303 hereof, the Company shall simultaneously
therewith deliver to the Trustee a certificate of an Expert (1)
stating that it is familiar with the provisions of such Senior
Note Mortgage Bonds and of this Indenture, (2) stating the
principal amount of such Senior Note Mortgage Bonds so delivered,
the stated interest rate (or method of calculation of interest)
of such Senior Note Mortgage Bonds and the stated maturity date
of such Senior Note Mortgage Bonds, (3) identifying the
Securities being issued contemporaneously therewith, and (4)
stating the fair value to the Company of such Senior Note
Mortgage Bonds. If the fair value to the Company of the Senior
Note Mortgage Bonds so delivered, as described in the certificate
to be delivered pursuant to this Section 1306(a), both (l) is
equal to or exceeds (A) $25,000 and (B) 1% of the principal
amount of the Securities outstanding at the date of delivery of
such Senior Note Mortgage Bonds and (2) together with the fair
value to the Company, as described in the certificates to be
delivered pursuant to this Section 1306(a), of all other Senior
Note Mortgage Bonds delivered to the Trustee since the
commencement of the then current calendar year, is equal to or
exceeds 10% of the principal amount of the Securities outstanding
at the date of delivery of such Senior Note Mortgage Bonds, then
the certificate required by this Section 1306(a) shall (1) be
delivered by an Expert who shall be independent of the Company
and satisfactory to the Trustee in its reasonable judgment and
(2) shall, in addition to the certifications described above,
state the fair value to the Company of all Senior Note Mortgage
Bonds delivered to the Trustee pursuant to Section 1301 hereof
since the commencement of the then current year as to which a
certificate was not delivered by an Expert independent of the
Company.

          (b)  If Senior Note Mortgage Bonds are delivered or
surrendered to the Company pursuant to Section 1305 or 1308
hereof, the Company shall simultaneously therewith deliver to the
Trustee a certificate of an Expert (1) stating that it is
familiar with the provisions of such Senior Note Mortgage Bonds
and of this Indenture, (2) stating the principal amount of such
Senior Note Mortgage Bonds so delivered, the stated interest rate
(or method of calculation of interest) of such Senior Note
Mortgage Bonds and the stated maturity date of such Senior Note
Mortgage Bonds, (3) if applicable, identifying the Securities,
the payment of the interest on and principal of which has been
discharged hereunder, and (4) stating that such delivery and
release will not impair the lien of this Indenture in
contravention of the provisions of this Indenture. If, prior to
the Release Date, the fair value of the Senior Note Mortgage
Bonds so delivered and released, as described in the certificate
to be delivered pursuant to this Section 1306(b), both (l) is
equal to or exceeds (A) $25,000 and (B) 1% of the principal
amount of the outstanding Securities at the date of release of
such Senior Note Mortgage Bonds and (2) together with the fair
value, as described in the certificates to be delivered pursuant
to this Section 1306(b), of all other Senior Note Mortgage Bonds
released from the lien of this Indenture since the commencement
of the then current calendar year, is equal to or exceeds 10% of
the principal amount of the Securities outstanding at the date of
release of such Senior Note Mortgage Bonds, then the certificate
required by this Section 1306(b) shall be delivered by an Expert
who shall be independent of the Company and satisfactory to the
Trustee in its reasonable judgment.

          If, in connection with a delivery or release of
outstanding Senior Note Mortgage Bonds, the Company provides to
the Trustee an Opinion of Counsel stating that the certificate
described by this Section 1306 is not required by law, such
certificate shall not be required to be delivered hereunder in
connection with such delivery or release.

          SECTION 1307.  Further Assurances.

          The Company shall cause this Indenture, any indentures
supplemental to this Indenture, and any financing or continuation
statements to be promptly recorded and filed and rerecorded and
refiled in such a manner and in such places, as may be required
by law in order fully to preserve, protect and perfect the
security of the Holders and all rights of the Trustee, and, at
its own expense, shall do such further lawful acts and things,
and execute and deliver such additional conveyances, assignments,
assurances, agreements, financing statements and instruments, as
may be necessary in order to better assign, assure, perfect and
confirm to the Trustee its security interest in the Senior Note
Mortgage Bonds and for maintaining, protecting and preserving
such security interest.

           SECTION 1308.  Exchange and Surrender of Senior Note 
                          Mortgage Bonds.

          At any time at the written direction of the Company,
the Trustee shall surrender to the Company all or part of the
Senior Note Mortgage Bonds in exchange for Senior Note Mortgage
Bonds equal in aggregate outstanding principal amounts to, in
different denominations than but of the same series and with all
other terms identical to, the Senior Note Mortgage Bonds so
surrendered to the Company. In addition, at any time a Security
shall cease to be entitled to any lien, benefit or security under
this Indenture pursuant to Section 404 hereof, the Trustee shall
surrender Senior Note Mortgage Bonds as provided in this Section
to the Company for cancellation. The Trustee shall, together with
such Senior Note Mortgage Bonds, deliver to the Company such
appropriate instruments of transfer or release as the Company may
reasonably request. Prior to the surrender required by this
paragraph, the Trustee shall receive from the Company the
following, and (subject to Section 601 hereof) shall be fully
protected in relying upon, (a) an Officers' Certificate stating
(i) the aggregate outstanding principal amount of the Senior Note
Mortgage Bonds of the series surrendered by the Trustee, after
giving effect to such surrender, (ii) the aggregate outstanding
principal amount of the related series of Securities, (iii) that
the surrender of the Senior Note Mortgage Bonds will not result
in any default under this Indenture, and (iv) that any Senior
Note Mortgage Bonds to be received in exchange for the Senior
Note Mortgage Bonds being surrendered comply with the provisions
of this Section 1308.

          The Company shall not be permitted to cause the
surrender or exchange of all or any part of a series of Senior
Note Mortgage Bonds contemplated in this Section 1308, if, after
such surrender or exchange, the aggregate outstanding principal
amount of the related series of Securities would exceed the
aggregate outstanding principal amount of such series of Senior
Note Mortgage Bonds held by the Trustee.  Any Senior Note
Mortgage Bonds received by the Company pursuant to this Section
1308 shall be delivered to the First Mortgage Trustee for
cancellation.

          SECTION 1309.  Terms of Senior Note Mortgage Bonds.

          Each series of Senior Note Mortgage Bonds delivered to
the Trustee pursuant to Section 1301 hereof shall have the same
stated rate or rates of interest (or interest calculated in the
same manner), Interest Payment Dates, Stated Maturity, and
redemption provisions, and shall be in the same aggregate
principal amount, as the related series of Securities being
issued.

          SECTION 1310.  Senior Note Mortgage Bonds as Security 
                         for Securities.

          Until the Release Date and subject to Article Four
hereof, Senior Note Mortgage Bonds delivered to the Trustee, for
the benefit of the Holders of the Securities, shall serve as
security for any and all obligations of the Company under the
Securities, including, but not limited to (1) the full and prompt
payment of the principal of such Securities when and as the same
shall become due and payable in accordance with the terms and
provisions of this Indenture or the Securities, either at the
Stated Maturity thereof, upon acceleration of the maturity
thereof or upon redemption, and (2) the full and prompt payment
of any interest on such Securities when and as the same shall
become due and payable in accordance with the terms and
provisions of this Indenture or the Securities.

          Notwithstanding anything in this Indenture to the
contrary, from and after the Release Date, the obligation of the
Company to make payment with respect to the principal of and
premium, if any, and interest on the Senior Note Mortgage Bonds
shall be deemed satisfied and discharged as provided in the
supplemental indenture or indentures to the First Mortgage
Indenture creating such Senior Note Mortgage Bonds and the Senior
Note Mortgage Bonds shall cease to secure in any manner
Securities theretofore or subsequently issued.  From and after
the Release Date, any conditions to the issuance of Securities
that refer or relate to Senior Note Mortgage Bonds or the First
Mortgage Indenture shall be inapplicable.  Following the Release
Date, the Company shall cause the First Mortgage Indenture to be
closed and the Company shall not issue any additional First
Mortgage Bonds or Senior Note Mortgage Bonds under the First
Mortgage Indenture.  Notice of the occurrence of the Release Date
shall be given by the Trustee to the Holders of the Securities in
the manner provided in Section 106 hereof not later than 30 days
after the Company notifies the Trustee of the occurrence of the
Release Date.
